You might have played some of the coin-operated arcade knock-offs of this Japanese original, but there's nothing like the real thing. The premise of the game sounds simple: you're given a list of dance steps to execute in time with the game's soundtrack. However, the action gets moving very fast, resulting in a pretty serious workout. The dance mat isn't included in this version, but you can play with controllers instead. An inventive Diet mode even tells you how many calories youre burning by playing.
