Everyone's eager to see what Sonic and Mario's first collaboration will look like, right? Well, here it is! The DS version, anyway. Mario & Sonic at the Olympic Games looks pretty okay! We don't really know what else to say about it. It's in 3D, and includes, at the very least, long jump, archery, hammer throw, and some kind of track event.
Sonic and Tails are participating in the manner of the ancient Olympians-- nude. We don't know if they've covered themselves in olive oil as the Greeks did, and we hope we never find out. We hope nobody ever finds out.
