I'm not much of a gamer, but I am very competitive and I remember (years ago) that there was this video game where it would display like "dance steps" that you had to follow on some kind of mat and it got faster and faster as you progressed. Does anyone remember this game? Is it still around or available? If so, I know that it would be a great help with losing weight. Or maybe there is some other kind of game that I can get that is along the same lines? Any thoughts or suggestions?? TIA.
