um i was pretty hardcore at DDR for a while (co-webmaster @
www.ddrmaniax.net) but like everything, it got old. one thing though, that just straight up
owns about it is the fact that it is EXCELLENT cardio. i'm buying a metal pad from Fry's Electronics (
www.outpost.com) over summer so i can get back into shape. i have stepmania as well, along with ddrmax/ddrmax2 for PS2.
good luck! you'll lose mad weight.
