If you havn't played it, do it, now! :)
man, this weekend i spent the nite at my friends house, and his bro bought DDR, the pad, and DDR:Konamix, and omg, its so freakin fun. We stayed up all nite playing, im sore as hell now, but it was seroisly worth it. It's a incredibly fun game and all of you should try it, very tiring though.
it's a great party game!
