i love dance dance revolution. its computer mediated physical activity. i think there is a big untapped market for those kinds of games. the new nintendo wii console looks to be targeting that market exactly - the wii controller looks to be fantastic for just that kind of game. i just saw a live video clip that has the player swinging the controller like a racket to play a tennis game. it looks to be extremely sensitive to motion, even twisting. thats gonna be fun.
