Nintendo created a new kind of game with the Wario Ware license. We had the idea to create a game that would be like "game sampling," where you have fun for a few seconds or minutes at most and then switch to another game, like zapping on TV. Wario Ware showed us it worked.

First thing is that the urban style was here to give us an overall direction for the ambiance of the game, but it was never something that stopped us making mini games, music, or visuals if we felt they would be fun, even though they wouldn't be a perfect fit to the urban theme. It was a direction, but never a restriction.

You can play with other players wireless, in a one-versus-one duel. In this mode you have to be the best at a specific playlist of games, while you throw "graphical disturbers" (shaking screen, reverse control, and such) at your opponents in order to complicate their mini games.
