Who all plays DDR? I've played the first three, but I only own the first one.
I play about two-three rounds every other day.
i play a little bit when we go to our cousins house. dont go often enough to actually get any better.
I play for about 3-4 hours every few days. Since I only play on heavy I can only go in 2 hour bursts without completely exhausting every muscle in my legs. But it pays off in the end, I can play any song on heavy now except for MAX3000 (the bpm is just blinding).

I haven't quite yet mastered heavy yet, I usually play on standard.
