Most arcade games encourage you to kick, bludgeon, and occasionally decapitate a conveniently gruesome-looking opponent while you sit on your butt and absorb EMF emissions. Dance Dance Revolution is not only closer to the spirit of Gene Kelly than the governor of California, it gives you a real aerobic workout, too. The idea is to stand on a platform with different colored panels and to step on a given panel when it lights up. The screen in front of you shows you which panels to step on, and if you don't step lively, or if you step on the wrong panel, well, you're not part of the revolution. The rhythmic patterns involved become increasingly complex as you attempt higher levels of Dance Dance difficulty, and the whole thing is very challenging, exhilarating, and, usually, bloodless.
