I wanna try it...but not sure if it'd be a good workout or not. I never played arcade style or anything... so I've never tried it. But I was just wondering 1) if anyone has tried this, 2) Is it a good workout, and 3) Do you HAVE to have a camera for your ps3 to use it or will the PS3 alone just do if you buy the DDR bundle game w/ the matt!? Thanks people.
