Microsoft released a lifestyle video of Kinect (previously Project Natal) with footage of a few games. The first game demoed is Kinect Adventures where two players control a jumping river raft. The track & field running game is from Kinect Sports, a camera controlled take on Wii Sports. The final game in the montage is Dance Central.
From a video alone, it’s hard to tell if the Kinect games are anything special, but those hold-your-hand up to stop the movie video controls are neat.
