Everything. The graphics are pretty poor along with the gameplay. The gameplay is reptitive and too easy. I foolishly rented this game hoping for a descent game but was wrong. This game sucks. I wouldn't recommend it to anyone unless you're looking for a good laugh or you're completely drunk of you're ass.
This game blows. I found this game to be horrible and I think its the worst game to date. It was easy and reptitive. You did the same thing over and over through the whole game. There were no different varietys of dances but rather the same exact thing over and over again until you won the "championship".
Overall Outcome: Stay As Far Away from this Title as you can!
