If the idea of getting your groove on in Kinect Star Wars had made you doubt your faith in humanity, but not your ability to shake your thang then Dance Central 3 ought to be the game you grab this week. The $15 you save will happily go to the DLC tracks you'll desperately want once you finish the campaign mode.
