WarioWare (series)
Warioware Inc. is a "company", managed by Wario, that produces micro games. Warioware games have been published for almost every Nintendo console, and their style varys from console to console, depends on it's features (e.g: for Nintendo DS, the games were based on touching the touch screen). Each game consists of Microgames-really tiny and basiclly simple games like popping baloons or spinning a coin, that are some of the times crazy like picking a nose. The games might seem simple, but as the player's level goes up, they are becoming more and more challenging.
Warioware also features several new characters, which can be found only there. Severals are Mona, Ashley, Jimmy T, 18 and 9 volt, Kat and Ana, Dr. crygor, Mike, and Super Zero and more. A nice feature in those games are toys-for every achievement done (like scoring a certain amount of points in a specific game) the player gets a toy to play with-like a mini piano, or a jelly to mess up.
Even if seems simple, Warioware games are true fun and entertaining.
