Perhaps the best "game" we saw yesterday at Microsoft's Kinect launch event was a Star Wars title. Why? Why don't you take a look yourself.
Take all this with a sizable grain of salt, of course, as you always should with on-stage demonstrations, but anyone that watches this and isn't at least a little excited (at the potential, if not the stilted performance from this obviously-not-actually-playing-the-game actor) is either lying or is a cold, barren husk of a person.
Oh, and don't bother checking your speakers, because there's no sound.
