Nintendo unveiled its latest party game, Game & Wario. Like other Game & Wario games, it only needs one controller. Five players can play, but four of them don't need controllers. At all. Just good eyes.
The mini-game is called "Fruits". In it, the player with the GamePad is a thief, and picks up the four or so fruit (in the demo, it was apples). The player with the GamePad knows which character he is, but the other players, who don't have controllers, must stare at the TV to see which person in the crowd is the thief. They're the G-men.
The thief can even use manholes to "warp" around the town. Then, after the time is up, the G-men must pick the the thief out of a line-up.
Game & Wario has sixteen games total, including one called "Gamer" in which you try to hide that you are gaming on the GamePad from your parents. Game & Wario will be out in the first part of next year, and it looks like it'll be another strong entry in the Wario series of party games.
