It's embarassing to play, but quite fun and good exercise. I'd like one at home. But I gotta get a PSX first.
What's better are the DJ games with the small keyboard and turn table. Now that's an addictive game. It basically works like the DDR machine but you play the keyboard and scratch the turntable instead of stomping. There are little freestyle scratching sessions here and there. COOL!! Haven't seen many of them in the states though.
