You damn kids, with your Dance Dance Revolution and Let's Dance and Rock Bandin'. Back in my day, we had this awesome music game that just used the Playstation controller - Parappa The Rappa.
Well, okay - maybe the game length was a bit low, and the options were a bit lacking. If I'm recalling correctly, there was no stage select, and only five "real" stages: kung-fu, driving, flea market, cooking and the bathroom, followed by the ending.
All of those stages were really, really well-done when it came to the rhyming and rapping, but heck, there weren't that many of them. The game's graphics seemed somewhat simplistic, so even if they added on some not-as-good songs, I think it would have helped the game out.
