The company that let grown men play with plastic guitars has made the best of the "you are the controller" Xbox Kinect games. We're not saying this can make you a good dancer, but you'll sure sweat like a fly guy. All the staples of what made Rock Band awesome work extremely well: tons of licensed music (hi, Lady Gaga!), great co-op battles and the ability to make shaking your whole body in front of your friends seem cool. Or at least as cool as those plastic guitars and drums were.
