Paper Mario: The Thousand-Year Door is a Nintendo Switch remake of the 2004 Nintendo GameCube game of the same name, and the first remake in the Paper Mario series. It was first announced during the September 2023 Nintendo Direct, and released worldwide on May 23, 2024.

The title features visually enhanced and updated graphics along with new gameplay features. However, it remains faithful to the style of the original game: the characters still use their designs from the original release (for example, Princess Peach keeps her pre-Mario Party 4 dress design), rather than the updated designs used in the following Paper Mario games. Many voice clips from the original game are also reused, in spite of voice actor changes since the original game's release, including Charles Martinet, Jen Taylor, and Scott Burns, former voice actors of Mario, Peach, and Bowser respectively.

Differences

New content

• The Nostalgic Tunes badge, resembling a Nintendo GameCube, can be bought from the Lovely Howz of Badges for one coin. Equipping it will revert the music to the original soundtrack. The game still plays tracks exclusive to the remake, however.
• Like in Paper Mario: Color Splash and Paper Mario: The Origami King, a concept art gallery, the Art Gallery, is available. It can be viewed from the menu, with more pieces unlocking throughout the game. The gallery includes concept art from the original game along with concept art specific to the remake. Art galleries are sorted by the story's chapters' locations, and are unlocked after collecting every Star Piece from that chapter's locations and taking the chapter's Crystal Star to the Thousand-Year Door.
• An in-game music player, the Sound Gallery, is now available from the menu. Music tracks are sorted by the story's chapters' locations in which they play, and are unlocked after collecting every Shine Sprite for that chapter and taking the chapter's Crystal Star to the Thousand-Year Door.
  • Equipping the Nostalgic Tunes badge allows the player to listen to the GameCube versions of the tracks as they're unlocked. While the badge is still equipped, tracks exclusive to the remake are disabled.
• A Purple Toad called the Battle Master can be found around the world. When talked to, he allows Mario to practice his attacks, in a similar fashion to the Action Command Dojo and Battle Lab from previous games. During his battles, Mario fights cardboard Goombas called Goomboards.
• A Little Mouser named Ian Foomus appears in the Trouble Center, offering advice to help with different troubles.
• The Hottest Dog recipe has been added and can made by mixing a Hot Dog with Hot Sauce.
• In the Glitz Pit, there is an exhibition match option when reserving a match. Exhibition matches allow Mario to select and fight any Glitz Pit team that he is currently ranked above (whenever or not he has fought them), and these battles do not have any battle conditions, nor do they affect Mario's ranking. As a result, the player can now easily obtain Tattle entries for enemies exclusive to the Glitz Pit if they failed to do so earlier. As a note, if the player wants to do a specific exhibition match after the chapter is complete, they'll have to rank up again, except for Prince Mush's battle.
• Upon completion of the Pit of 100 Trials at least once, a Mover outside the entrance provides fast-travel to the 50th floor for 300 coins.
• Two new bosses have been added:
  • Prince Mush can be challenged at the Glitz Pit. To unlock him, the player must complete Jolene's trouble "Help wanted!", and then wait some time to receive an email from her talking about new Exhibition Matches and that Mush is training. After waiting some more time the player will receive another email, this time from Prince Mush, issuing a challenge. By heading back to the Glitz Pit and selecting Exhibition Match in any league, the player can then challenge him to a fight. Mario will receive Prince Mush's Belt if he defeats him.
  • Whacka can be found in the Pit of 100 Trials and can be defeated to receive the Gold Whacka Bump. In order for it to appear, the player needs to defeat Bonetail, hit Whacka in Keelhaul Key enough times to make it disappear, receive an mail called "RDM Extra Issue" saying a mystical creature has been seen deep in the pit, and traverse to floor 100 of the Pit again. Returning to the Pit and fighting Whacka again yields a regular Whacka Bump.
• The Creepy Steeple Boo can be found in the storeroom after beating Doopliss the first time and becoming a shadow, where he will quiz Mario on various parts of the story. There are six quizzes in all, with the last quiz having 15 questions in total and only being available during the post-game.
• Three trophy items have been added as rewards for Journal completion:
  • The Cooking Trophy for obtaining all recipes
  • The Badge Trophy for obtaining all badges.
  • The Tattle Trophy for completing the Tattle Log.
• Mario is awarded with a Gold Medal for obtaining all three trophies. It has the effect of visually turning him gold, and the effect will stack with the L Emblem and W Emblem.
• There are ten more Tattle Log entries compared to the original game. Amongst these include the Goomboard, the Fuzzy Horde in Shhwonk Fortress, the X-Naut horde in Lord Crump's second fight, and the two new bosses, Whacka and Prince Mush.
  • The second fights of Bowser, Doopliss, Beldam, and Marilyn, and the 2nd phase of the Shadow Queen now have separate Tattle Log entries. As a result, if they were Tattled in their first battles, their HP is not immediately shown in their rematches until they are Tattled again.
• A few new emails have been added, such as one from Professor Frankly informing Mario about the First Attack badge, or the Toad Bros. Bazaar informing Mario when the Contact Lens have been restocked.
• A Notes tab has been added to the menu. This lists the active Trouble Center requests, and any of Merluvlee's predictions that are still relevant.
• A Toad was added in the Petalburg shop to give advice about POW Blocks.

Gameplay changes

Menus and controls

• The player's play time for their save file appears only on the file select screen; it can no longer be seen in the game's menu.
• The player can longer scroll through their list of items and badges using the and buttons as that is used to scroll through the menu screens instead.

• The Mailbox SP mail system has been reworked to function similarly to the notifications system from Paper Mario: The Origami King, where alerts no longer affect the player's ability to navigate in-game.
• Like Paper Mario: The Origami King, the last saved point can be accessed from the Game Over screen, and the current scene can also be played again. This time, it no longer limited to certain situations and any scene the player was last in can be played again.
• When levelling up, the player has to press a direction with the to select an option, rather than HP being the default.
• If the player is wearing an FP Plus or HP Plus, increasing their FP or HP respectively, when levelling up, the higher numbers for increasing FP or HP will take into account the badges worn.
• The Nintendo Switch system keyboard is now used when prompted to name Yoshi Kid instead of an in-game one. However, all other text input prompts, such as the ones for Doopliss' name and the access code in X-Naut Fortress use an in-game one.

Field

• On the field, Mario can swing his Hammer forwards and backwards like in entries since Paper Mario: Sticker Star.
• On the field, bushes can no longer be interacted with when near them, however they can be crumpled with the Hammer for the same effect, as with Paper Mario: Color Splash. Incidentally, Bowser can still interact with bushes in the same manner as in the original game.

• The Paper Plane mode stays at a fixed distance from the ground until it has transcended the horizontal width of the activation panel.
• The player can now use the Hammer to locate flippable panels on the ground containing Star Pieces, though the Hammer cannot flip them. In the original game, this is not possible with any Hammer; the only way to locate panels is to use Spin Jumps.
• When using Koops's partner ability on the field, a green circle marker with an arrow is created where Mario jumped off Koops, the arrow indicates the direction Koops's shell will launch.
• Breaking large blocks using the Super Hammer or the Ultra Hammer now requires Mario to charge beyond the minimal amount to break them.
• When the player levels up, all party members are fully revived instead of just the current one in the lead.
• When riding on Yoshi, the player now loses momentum when riding off edges, making traveling down them slower than in the original game.
• The player can now talk to NPCs while riding on Yoshi, although he gets off Yoshi to talk.
• A prompt to check interactable elements in the scenery was added, hinting on what the player can do with them.

Warp Pipes

• Warp Pipes are now entered by pressing , and a prompt appears above one to tell the player to do so. In the original game, entering them requires tilting down on the .
• When emerging from a Warp Pipe, Mario automatically jumps out and forward.
• A new warp room similar to the "One World, One Pipe" room in Musée Champignon from Paper Mario: The Origami King appears, replacing the original pair of warp rooms across Rogueport Underground. When entering this room after taking a Crystal Star to the Thousand-Year Door, the Magical Map is held up in a similar fashion, and unlocks a pipe leading to a locale for that Crystal Star's chapter. There are seven pipe slots instead of four, and a pipe leading from this room to Rogueport plaza can also be opened. The door leading to it on the right side is hidden and requires Flurrie to reveal.
  • Pipes 1, 2, and 6 lead to the second area of Petalburg, the outside of the Great Tree, and the fountain in Poshley Heights in the same spots as the original game.
  • Pipe 3 leads to Glitzville, southeast of the juice shop.
  • Pipe 4 leads to the second area of Twilight Town.

  • One was added in the Palace of Shadow, leading from the Depths room before the Shadow Queen back to the entrance of the palace.

Save and Recovery Blocks

• Just like Paper Mario: Color Splash onward, when hitting a Save Block, the game now saves immediately instead of asking whether to save the game or not. This also applies when the game transitions to each character segment and when the game is completed.
• New Save Blocks have been added or relocated:
  • The one near the pedestal of The Thousand-Year Door is moved to the entrance of the Pit of 100 Trials.
  • The one in the first area of Boggly Woods is moved to the second area, allowing the player to save before the Three Shadows fight.

  • One appears in the third floor of Hooktail Castle and costs 10 coins to use.

• Getting hit by enemy projectiles in the field no longer initiates a battle, instead damaging Mario on the spot like in entries since Paper Mario: Sticker Star.

• Dark Bristles can no longer be hit by a First Strike with the Super or Ultra Hammer.

Specific battles

Text changes and localization

• The game has now been translated into Chinese (Simplified and Traditional), Dutch, Canadian French, Latin American Spanish, and Korean. The original was not available in these five languages since, at the time, Nintendo of Europe did not do Dutch localizations, Nintendo of America localized games into English only (not French or Spanish), and Nintendo of Hong Kong and Nintendo of Korea did not yet exist.
• Several translation errors, typos, and continuity errors from the original game have been fixed:

  • Any instance of Yoshi Kid calling Mario by his actual name instead of Gonzales before the ending has been corrected.
  • Peach's emails have been slightly altered to better align with the actual story developments in her intermissions:
    • In her first email, Peach now states that the X-Nauts "may be aware" that Mario has the map rather than that they "are already aware", and she does not encourage Mario to collect the Crystal Stars, as she has already learned that Mario collected the first.
    • In her third email, Peach now states that the X-Nauts are seeking the Crystal Stars to claim the legendary treasure, as she had learned this from Grodus (she previously stated that she did not know what the Crystal Stars did).
    • In her fourth email, Peach now states that the X-Nauts plan to "unseal" the demon's spirit held behind the Thousand-Year Door, rather than "revive" it.
  • The Iron Adonis Twins are now correctly referred to by this name in all dialogue in English. In the original game, certain instances of dialogue incorrectly refer to them by their descriptor "The Armored Harriers".

  • Little Mousers are now called by this name, rather than being called Squeeks like in the original game.
  • Gloomer is always referred to by his proper name instead of as "Freddy" when he is first met.
• The descriptions of many usable items and badges have been clarified or had false information removed.
  • In the original game, the descriptions of the Thunder Bolt and Thunder Rage falsely claimed that they could stun enemies. In the remake, this was fixed and changed to say that they deal 5 damage to enemies.

• Some English character dialogue has been altered slightly from the original game.

• A scene from both the original English and Japanese versions of the group of enemy Goombas encountered early in Rogueport Underground cat-calling Goombella (saying red, and her defending herself saying red), has been omitted. The dialogue now instead has the enemy Goombas insult Mario for being from the surface.
• In both the original English and Japanese versions, Goom Goom describing that the girl he wants would be younger than him (red) which university student Goombella ends up meeting, has been omitted. He now describes his criteria as green.

• Lahla now wears cat ears in the Japanese version like in all other regions, rather than bunny ears like the original in that region.
• Hooktail's weakness is stated to be frogs instead of crickets, like in the original Japanese script. As a result, the Attack FX R badge found in Hooktail Castle, used as a weakness for Hooktail when equipped, has been replaced with Attack FX G, which now makes frog noises.
• The Yoshi is now referred to as Yoshi Kid in areas such as the name of his theme in the soundtrack.
• In the German and Spanish versions, the translation error where Toadette was incorrectly referred to using the name of Vanna T. from the first Paper Mario (which was likely due to the two characters sharing the same name in Japanese) has been corrected.
• The red have been renamed to the "Three Shadows," a more accurate translation of their Japanese name, the Shadow Trio. Also, Vivian now accidentally refers to the group as the green instead of red in the original game. This is also a more accurate translation of the Japanese text. After this occurs, Beldam states green.
• Vivian's portrayal as a transgender woman is more overt, with the Japanese version adding in dialogue where she says green (green) Her party member description is changed from red (red) to green (green) This portrayal is also reflected in the remake's English localization, whereas the English release of the GameCube version omitted all references to the subject.
  • The Japanese script removes lines that refer to Vivian as male; for example, Beldam's line red (red) is replaced with green (green) Goombella's tattle about Vivian also removes any mention of her gender.

• Enemies originally written with abbreviations now have their full names displayed at all times.

• In the Japanese script, Rawk Hawk's title has been changed from red (red) to green (green); this is likely due to nuclear power generation being a controversial topic in Japan after the 2011 Tōhoku earthquake and tsunami.

• The Glitz Pit match conditions now show up onscreen throughout the entire duration of the battle, and now indicate whether they have been met or not.
• The Allergic status effect's description has been changed from red to green, which more accurately describes its effect.
• Certain dialogue was altered in the Chapter 5 intermission. When Peach is made invisible, TEC-XX states that her dress still being visible is a "tactical error"; unlike in the original game, he does not explicitly ask for Peach to remove her dress.

• In the Italian version, the name of the University of Goom is changed to accommodate its rename in Paper Mario: Sticker Star.

• The Chuckola Cola is now magenta-colored in Japan, like all other regions.
• Wonky's tale "Z Button" has been completely removed, pursuant to the removal of being able to view previous dialogue messages. As a result, Wonky has one less tale than in the original game.

• The Palace of Shadow Tower now recites the passages from its signs after all Tower Keys have been used: "The stars up in the heavens shone; Carrying the lore of the sky; Carrying secrets from on high; By skill and might, engraved in stone. Stones to rival the celestial spheres; The seven hewn by a fell hand; Feared far and wide across the land; Master of shadow, queen of fear."

• The separate Latin American and Castilian Spanish translations mean some characters have different names between the two versions. For example, Swindell is named Fraudio in Latin American Spanish and Serrallonga in Castilian Spanish.
• Charlieton's Castilian Spanish name, Ahmed, has been changed to "M. Baucador" (a pun on embaucador, "trickster"), likely due to the negative implications behind giving a shady salesman character an Arabic name.
• Dupree's Castilian Spanish name has been changed from Afro to Rolfunk.
• Many of Merluvlee's predictions have been modified slightly to change how she refers to the place. For example, Fahr Outpost goes from "the cold village" to "the snowy outpost" and "the train-refueling depot" to "a midpoint station where a beautiful train frequently stops." Minor corrections have also been made, such as referring to an "archway of roses" instead of a "rose hedge" in Poshley Heights, or the "chests and barrels" instead of the "chests and boxes" in Hooktail Castle's treasure room.
• Obtaining a new item now says "You got [item]", to avoid typos such as "You got a Super Boots".

Graphical changes

• The entire game has a higher-resolution, more crafted appearance similar to recent entries starting from Paper Mario: Sticker Star onward, though it keeps the original game's smoother animations, rather than the choppier animations seen in those entries. For example, the characters now have a slightly thicker paper texture similar to cardstock, while the pigs have visible seams on them, and coins are fully modeled rather than sprites. As another example, the Crystal Stars have a more realistic shiny texture than the original game. To go alongside these changes, dynamic lighting is now present extensively in many areas.

  • Mario shrugs his shoulders when unable to push heavy objects or missing in the crane game in the X-Naut Fortress.
• More characters can be seen from behind, such as Mario's partners, unlike in the original, where they are shown in a frontal profile regardless of the camera angle.
• Due to the widescreen resolution, the HUD elements, transitions, and some interiors have been redesigned to accommodate the extra horizontal space. Framing in several cutscenes and some background scenery has also been readjusted to go alongside these changes.
• The character artwork in transitions is now shaded. The transitions themselves also go by much faster compared to the original game.
• More visual aids for points of interest have been implemented, such as a sign that displays an icon with tacked papers above the door to the Trouble Center building, and the pipe leading to Petal Meadows now resting on a grassy platform.
• Areas with a dotted background, such as the backgrounds surrounding partners when they join Mario's party and the area where the black chest face resides are now fully 3D environments, rather than static backgrounds.

• When reading Ghost T.'s diary, the scene now has a black-and-white grain filter on it and now fades to black slowly rather than spinning around.
• The Galley Pot is now gold-colored instead of silver.
• The magenta Smorgs are not visible in the cutscene before the battle.

Fahr Outpost

• The Moon is now seen when Mario and his party are launched from the cannon in Fahr Outpost.

The Moon

• There is now black fading on the edges of the screen that is not present in the original game.

X-Naut Fortress

• Mario's 8-bit sprites when he comes out of the shower in X-Naut Fortress sport a slightly different design compared to the original game.

Palace of Shadow

• The Palace of Shadow Tower now has glistening star patterns on the ground. The eight doors now have yellow star patterns above them that change to blue when the player obtains Tower Keys from their rooms. There is also a graphic that shows when the player passes through a wall in one of the rooms.
• The Shadow Queen's design has earned minor, lucid changes; her star-filled body and hair are coated in a darker purplish hue with her crown now bearing a shiny, glossy light reflection.
• The dark flames from the Coffin Hall's candles now have glowing white tips instead of having an all-dark purple coloration.
• When the candles flames change color, the color of the rug changes to blue instead of remaining red in the original game.
• Hand-like shadows cover the world when the Shadow Queen awakens instead of regular shadows, in a similar vein to the "Night on Bald Mountain" segment from the Disney film Fantasia.
• Mario now goes first to check Peach after the Shadow Queen is defeated instead of his partner.

Cutscenes

• The storybook intro sequence is now animated. If all four save files currently are empty, the intro also now comes after the title screen after starting a new save file rather than before it..
• In the opening shot of Mario's house, Parakarry has his arms raised to the mailbox as he delivers Peach's letter, as opposed to the mailbox just rattling with him next to it.
• The Mario Bros.' House has a group picture of Mario's partners from the first Paper Mario, and during the ending cutscene, the group picture of Mario's partners from The Thousand-Year Door, as a call-forward to Super Paper Mario featuring said pictures. The map inside the house has also been changed to the world map from Paper Mario, and the exterior of the bedroom was sectioned to match its design from that game.
• When Peach's letter is being read in the opening cutscene, it is now displayed over a black background before cutting to the first view of Rogueport, where the letter itself no longer becomes visible at the bottom of the screen.
• In Princess Peach's post-Chapter 3 intermission, the conversation between Sir Grodus and the disguised Peach now plays out as a cutscene, whereas in the original game, Peach had to walk up to Grodus to talk to him.
• Before the fight with Doopliss at the top of Creepy Steeple, the bell now rings.
• Just before the start of Chapter 5, the X-Naut reporting the infiltration is no longer standing behind a wall but behind the barrels behind the ship.
• In the beginning cutscene of Chapter 5, when the S.S. Flavion is surrounded by Embers, the Embers now attack the ship by pushing it, causing Four-Eyes and Admiral Bobbery to be thrown overboard, followed by the ship being turned over on its side. In the original game, Four-Eyes abandons ship, and the S.S. Flavion eventually sinks.
• When the Excess Express arrives at Riverside Station, Doopliss (in his Zip Toad disguise) is being shown tied up in ropes before breaking free.
• The entire post-Chapter 7 ending sequence in the X-Naut Fortress is significantly modified:
  • During TEC's last speech to Mario, his dialogue gradually begins to tremble (at first just the ellipses, and then the entirety of the text).
  • Rather than the standard X-Naut Fortress music, the cutscene is at first silent. When TEC mentions that he will cease to function, a somber arrangement of Peach's theme begins playing. This somber arrangement continues to play as Mario makes his way to the teleporter room.
  • The line "TEC system failure reported," has been removed. Instead, when TEC shuts down, the red hazard lights immediately turn on with an accompanying sound effect.
  • The elevators no longer say "Choose your destination," after TEC shuts down, instead simply showing the floor prompt with no dialogue attached.
  • After Mario takes the teleporter, the lights in the fortress shut down, followed by an alarm, signaling the fortress's impending destruction.
  • TEC's line "Peach...Goodbye..." is no longer displayed in a text box, and instead appears in the center of the screen. The somber arrangement of Peach's theme plays one last time over this scene, instead of ambient sound effects as in the original.
• In all regions, the bad ending shown when Mario accepts the Shadow Queen's offer reflects the Japanese version of the original game. Mario takes on the appearance of Doopliss's copy (retaining the Emblems he has equipped), rather than simply having an angry expression. Additionally, the music fades out, and the ending text in this scene now takes up the whole screen, rather than being confined to a text box.
• Several characters are added to most areas during the scene where they encourage Mario through the Crystal Star in his battle with the Shadow Queen:
  • The residents in Rogueport now show up when the Crystal Stars appear in the town.
  • Prince Mush in Glitzville. An error from the original game is also corrected where Shellshock appeared speaking like King K, now King K himself appears in Shellshock's place.
  • The shopkeepers in Twilight Town.
  • The Traveling Sisters Three and Dupree in Keelhaul Key.
  • The Excess Express staff in Poshley Heights.
  • General White in Fahr Outpost.
• In the prologue, after escaping from Lord Crump and the X-Nauts, Mario and Goombella now turn around to acknowledge the fight between Tony/Vinny and Gus/Garf.
• In the final battle, Frankly is shown from a different angle in his cutscene.
• In the epilogue after the final boss, a curtain no longer descends before showing Flurrie in the "Paper Mario" stage play.
• Instead of the camera zooming towards Mario in the ending cutscene, a snapshot of the scene now shows, which then transitions into an illustration of a page in the storybook seen in the opening cutscene, in which it then closes and the desk lamp the book was next to shuts off.

Audio changes

• The game's music has been rearranged with new instrumentation and in a similar style to later entries in the Paper Mario series. Furthermore, several songs are extended with new melodies. The original soundtrack can be played via equipping the aforementioned Nostalgic Tunes badge.
  • Several areas have dynamically changing songs. Each level of Rogueport Underground now has its own music, as does the X-Naut Fortress.
  • Similar to Paper Mario: Color Splash and Paper Mario: The Origami King, the main battle theme changes to different arrangements specific to each area. Also like in the final areas of both games, the field theme continues playing during battles in the Palace of Shadow (except inside the Tower).
  • Similar to Paper Mario: Color Splash and Paper Mario: The Origami King, each battle theme has its own unique victory theme to go along with it. However, the unique version of the victory theme that plays when Mario's current partner has run out of HP has been removed, and does not play even with the Nostalgic Tunes badge.
  • Like the first Paper Mario, as well as all games since Paper Mario: Sticker Star, each battle theme's intro changes depending on whether the player or the enemy gets the first strike.
  • Like in Paper Mario: The Origami King, each battle theme changes to a quieter "thinking" variant if no action is made for some time.
  • The regular battle theme begins with an arrangement of the Ground Theme motif from Super Mario Bros..
  • Bowser's theme in this game now incorporates parts of "Bowser's Castle" from Paper Mario: The Origami King.
  • The track that plays in the room where the Thousand-Year Door dwells now has variations in which different instruments join each time a Crystal Star has been collected, similar to the world map in Paper Mario: Color Splash and Toad Town in Paper Mario: The Origami King.
  • When Peach waltzes with TEC, there are now various different versions of the music that can play. If Peach messes up her steps and performs worse, the music becomes off-key, and eventually a metronome is added to make the rhythm easier to follow.
• New music tracks have been added.
  • When Parakarry delivers the Magical Map to the Mario Bros.' House and when talking to Lady Bow in the post-game, an arrangement of the title theme from the first game can be heard.
  • As Luigi reads Princess Peach's letter at the beginning of the game, an arrangement of "Inside the Castle Walls" from Super Mario 64 plays.
  • A new ambient theme plays while lingering on the chapter introduction screen.
  • All of the partners, as well as several other characters such as Goldbob and Flavio, now have their own themes that play when they are being focused upon.
  • New battle themes have been given to several of the game's bosses, with certain bosses that originally shared boss themes, such as Magnus von Grapple 2.0, Gloomtail and Bonetail, receiving new renditions of their original themes and Atomic Boo receiving its own unique theme. Bowser's first battle in the Glitz Pit also uses a new theme instead of his overworld theme.
  • The Peach intermissions have more unique music, such as a "stealth" theme when she is sneaking around in the Chapter 3 and Chapter 5 intermissions, and a "tense" theme in certain moments that had no music in the original.
  • The credits theme has been replaced with an entirely new one incorporating leitmotifs from various tracks throughout the game.
  • When Koops reads what he thinks is his father's letter there's a new music that plays.
  • When reading Ghost T.'s diary, a new horror track plays alongside it.
  • When leveling up, there's a new jingle every 10 levels corresponding to Mario's Rank improving.
  • Music now plays when Mario and his partner lose to the Iron Clefts in the Glitz Pit.
  • The terminals in the Glitz Pit that resemble the Game Boy Advance now make the sound of an actual GBA turning on when activated.
  • During the time in Chapter 4 when Mario is reduced to a shadow, three new, eerie ambient tracks play in place of the Twilight Town, Twilight Trail and Creepy Steeple themes.
  • The intro portion of Doopliss's theme music now plays when he removes his Zip Toad disguise.
  • A new track now plays when exploring the back entrance and underground portions of Riverside Station. In the original game, the Riverside Station theme plays in the former and no music plays in the latter.
  • The ending montage with Goombella features each partner's new theme rather than the standard music of each location.
• Sound effects are of an overall higher quality.
• There is more voice acting.
  • In place of the sounds of message balloons appearing and disappearing, characters are now given unique talking sounds during dialogue, similar to the Mario & Luigi series and the Paper Mario series from Sticker Star onward. Luigi, Princess Peach, and Bowser, for example, have talking sounds similar to their voices; Kammy Koopa uses talking sounds similar to Kamek's current voice.
    • NPCs of other species use vocal effects from other games in which they appear. For example, Koopa Troopas (including Koops), Thwomps, and Bob-ombs (including Admiral Bobbery) speak with the vocal effects used for them since Super Mario 64. Piantas' vocal effects are taken from those in Super Mario Sunshine, and Boos' vocal effects are taken from those in New Super Mario Bros.
    • Characters of the same species can have variants in their speaking pitch; for example, Francesca speaks in a higher pitch than other Piantas, and Admiral Bobbery speaks in a lower pitch than most Bob-ombs.
  • Audience members now use voice clips of their respective species. Consequently, the audience no longer screams when leaving the theater in panic, or when attacked by certain bosses.
  • When the Boos escape the box in the Creepy Steeple, they can be heard laughing.
  • Chain Chomps now use their signature barking sound when they lunge at Mario on the overworld. Likewise, the "talking" Red Chomp of Chomp Country now uses a portion of said bark as its talking sound.
  • Atomic Boo uses King Boo's voice samples for its sound effects.
  • Flavio's "singing" during Chapter 5 is now audible (performed by a kazoo).
  • Princess Peach's scream when being possessed by the Shadow Queen is audible.
  • Mario makes no vocal sounds while he is a shadow during Chapter 4.
  • Mario now whistles in his sleep, similar to Super Mario 64.
• There is a sound effect when the player presses A to start a chapter.
• When Mario stands on top of a plane panel or boat panel, a sound effect reminiscent of Magic Circles from Paper Mario: The Origami King can be heard.
• There is a sound effect when Mario uses Paper Mode between two walls.
• The sound effect when enemies are defeated is reminiscent of the one heard in Paper Mario: Sticker Star and Paper Mario: Color Splash.
• The healing sound effect is the same as the one from Paper Mario: Sticker Star onwards.
• The sounds the coins make when collected are now the same sound from Super Mario 3D Land, just like in Paper Mario: The Origami King.
• The spiked damage sound effect is the same as the one from Paper Mario: The Origami King.
• The Ground Theme and the Family Computer Disk System startup jingle are now reused from the original console, rather than being remixed like the original game.
• Lord Crump's theme now plays when Lord Crump is talked to during the post-Chapter 5 Bowser segment, as well as the epilogue scene with the X-Nauts. In the original game, this theme only plays during two cutscenes in Chapter 2.
• The train bing bong sound is now a variation on the Excess Express theme.
• Pennington's theme plays when he confronts Bowser in Poshley Sanctum.
• The eerie howling sound that periodically plays in Creepy Steeple is no longer present; neither are the choir voices in the Palace of Shadow.
• When Peach is undressed during the Chapter 5 intermission, the sound of bare feet on tile can be heard as she walks. In the original game, a quieter shuffling sound effect was used instead.
• Princess Peach's theme no longer plays when Mario explores the western rooms of Sublevel Four of the X-Naut Fortress.
• The second theme of the Palace of Shadow now plays in the corridors leading to Gloomtail's lair even if the orrery in the Palace of Shadow Tower has not yet been activated.
• The Chapter 8 introduction theme is replaced by continuing the current theme for the Thousand-Year Door room.
• There is no music after Grodus escapes from his battle.

Miscellaneous

• Save files can no longer be named, much like entries from Paper Mario: Sticker Star onward.
• On the file select screen, the player now uses to copy files and to erase them. File 1 and 4's colors have also been swapped, with 1 being blue and 4 being yellow.
• Save files now depict Mario (including his alternate colors) and his current partner on the right of them and the date and time the game was last saved below it.
  • Completing the game results in a medal appearing on the top left of the save file.
• Only Mario is present on the title screen when the game is started for the first time; Mario's partners will each be added to the title screen when they join him, including Vivian, Admiral Bobbery, and Ms. Mowz, who were not present in the title screen of the original game. The characters and the hills on the background also now animate.
  • After Goombella joins the team, the curtains open earlier on the title screen.
  • Peach, Bowser, and Kammy Koopa appear on the title screen after clearing their segments in Chapter 1.
  • Completing the game now results in Luigi appearing on the far left of the title screen, with confetti getting launched.
• Like in Paper Mario: The Origami King, any button can be used to start the game, whereas in the original, only was used.
• A settings page is available in the menu list, allowing the ability to adjust the rumble and brightness settings and exit to the title screen.
• The credits have been overhauled to now be modeled after a curtain call of a stage play, with the carousel of character silhouettes being replaced with the characters walking on the battle stage alongside various skits that occur during it. The credits now end with a wide group shot of the major characters and the audience.
  • Parakarry is the first character in the credits rather than Luigi, who is an audience member instead.
• Copyright information is not present at the end of credits.
• The game's European and Japanese age ratings have been raised to PEGI 7 and CERO B, up from PEGI 3 and CERO A of the original game, respectively.

Promotion

The battle stage diorama from the European My Nintendo Store

By pre-ordering the game through the My Nintendo Store in Europe, customers would receive Mario, Goombella, and Yoshi Kid keychains. A bundle containing the game and a buildable diorama of the battle stage including several enemies and characters from the game was also made available on the store.

In Australia, an A5 magnet sheet and a set of foldable Mario paper planes were included as pre-order bonuses for the game from EB Games and JB Hi-Fi, respectively.

In GameStop Canada, a slipcover for the Nintendo Switch case depicting the original GameCube cover is included as a pre-order bonus.

Prior to the game's release, Nintendo of Europe e-mailed a survey about the role-playing games of the Super Mario franchise to a select number of newsletter subscribers. The survey asks participants to state their opinions on topics such as the gameplay and characters of the Paper Mario series, the Mario & Luigi series, and Super Mario RPG. A different survey was temporarily released by Nintendo of America via the Qualtrics website, which asked participants about their general gaming experience as well as featuring questions specifically on the subject of Paper Mario: The Thousand-Year Door for Nintendo Switch.

On May 26, 2024, Nintendo of America issued a printable paper airplane template with a design featuring elements from the game. As well, they published a video tutorial wherein John "ThePaperAirplaneGuy" Collins, holder of the Guinness World Records title for the farthest flying paper airplane from 2012 to 2022, explains how to fold the template. On May 30, 2024, Nintendo of America promoted the game with yet another paper plane–related product in the form of a Snapchat Lens that folds a user's photograph into an AR paper plane in a fashion reminiscent of the game's Plane Mode.

Descriptions

North American Nintendo eShop

Join Mario on an epic paper-adventure to collect the Crystal Stars before the X-Nauts do!

The nefarious X-Nauts are after the treasure behind the Thousand-Year Door! With a map from Princess Peach, and the help of a few locals, Mario journeys through a colorful world made of paper to find them first. To prevail in this quest, you’ll have to level up Mario and his friends, master timing-based attacks and badges to impress the audience on the stage of combat, and make use of all the abilities that come with being cursed—er, conveniently made of paper—like folding into a plane to cross big gaps or turning sideways to slip through narrow openings.

Leaf through a storybook world with charming characters in every fold

Surprises abound in this deep and engaging tale, where everyone’s got something to say and it’s often not what you’d expect. Mario will meet all kinds of interesting folks on his journey, like the upbeat and studious Goombella and the shy but determined Koops. Some of these characters will need your help with their own quests, or even join your party. Others, like Peach and Bowser, have stories of their own that you’ll play between Mario’s chapters!

A classic turns the page, bringing fresh visuals and updated features

Twenty years after the original game on the Nintendo GameCube™ system, this version for the Nintendo Switch™ system has revamped graphics, and a suite of additional changes that make the game easier than ever to enjoy.

Pre-release and unused content

Various badges that also went unused in the original game have graphics in this game, complete with a few having names. These include Mega Jump, Mega Quake, Mega Smash, Triple Dip, Triple Dip P, Lucky Day P, Pity Flower P, and unused alternate designs for Damage Dodge and Damage Dodge P.

Trivia

• This is the second Super Mario game after Super Mario Odyssey to receive a B rating by the CERO in Japan.
• Despite being released in 2024, the copyright text on the bottom of the title screen and some promotional material only says 2004 for unknown reasons.
• Just like in the original game, the intro to the title theme has a different melody if the system language is set to Japanese. The Nostalgic Tunes badge also accounts for this difference.
