Attention couch Olympians, a brand new demo of -- ahem -- Beijing 2008 - The Official Game of the 2008 Olympic Games is now available on Marketplace. According to the dash details, as provided by our good buddy Major Nelson, there are 38 events in which to compete. All of them are guaranteed to "challenge a player's time, speed and co-ordination." Somehow, we get the feeling that a lot of button mashing and stick twirling will be involved. Still, if you think you've got it in you to best a digital Michael Phelps, give it a go.
