I just purchased a PS3 and I would like to purchase a DDR game. However, I’m totally confused about which game I should purchase and which dance pad would be needed. Can you use the games for PS1 and PS2 and play them on PS3? Also, can you use the dance pads? I don’t want to spend a lot of money on sleek metal dance pads. I prefer the cheap ones that sometimes slip from under your feet. Please help.
