WarioWare

 It's hard to think of a game more suited to exploiting the fun of a gyroscope sensor—the built-in motion sensor that detects rotations of the GameBoy Advance—than WarioWare, so kinetic and physical were its mini-games even when they merely involved single button presses.

Game Description: WarioWare: Twisted! brings back the fun of teh 5 second microgames that made the first WarioWare such a hit. Dr. Cry-Gor is back and he changes things by adding a new gyroscope to Wario's GBA. Now you can control the action by rotating the entire GBA and pressing the A Button. Along with this new motion sensor, the cartridge has a rumble pack for force feedback. Tons of crazy, spin-controlled games are waiting for you!

Beyond this mocking, intentionally cheap and campy experience is a concise (though admittedly incomplete) cross-section of some of both the classic and the forgotten moments in Nintendo's videogame history, and a throwback to those beloved twitch-games of yore.
