Editing Super Mario Galaxy 2

In ''Super Mario Galaxy 2'', levels are accessed linearly via a world map. This is a departure from the proceeding 3D ''[[Super Mario (series)|Super Mario]]'' games and is comparable to the 2D ones. The player accesses worlds from the [[Starship Mario]], a small planetoid that serves as the game's hub. When Mario steps on a panel on the starship's bow, the perspective rapidly pans out to a view of the current world. Starship Mario – itself shaped like Mario's head – is a stand-in for Mario himself that can be moved between galaxies like a cursor. Galaxies are unlocked unilaterally – collecting a Power Star within one opens up paths to the nearest galaxies (with the exception of [[World S]] where each galaxy must have at least one mission completed to access the next), the final galaxy of each world is a boss galaxy that features a fight against [[Bowser Jr.]] or [[Giant Bowser|Bowser]]. Defeating them unlocks the following world. The earliest worlds have the simplest, most straightforward paths between galaxies, but the paths become more divergent with each world, enabling the player to visit galaxies in whatever order they want (see right).
