I play DDR, and im a tubby 26yr old surly sonofabitch
The DDR scene here in vegas is pretty big, but the casinos dont really keep the machines in top form. It doesnt help that one of the last pure arcades in town (non casino owned) closed recently, and they had every DDR machine ever made in top condition. They only charged 50 cents a play and you got 5 songs per play. Since they closed a lot of kids are moving on to Pump it Up, or Para, or TechnoMotion, or IIDX..
I'm personally looking to either making a MAME cabinet for DDR, or just buying a machine this year. They arent that expensive, about 2 grand or so.
