Sonic Free Riders demo now available on Xbox Live

If you've got a deep well of love for your Kinect, but a shallow reservoir of software for your Kinect, you can add a little something-something to the pile at no charge. If you're an Xbox Live Gold subscriber, you can now download a demo for Sonic Free Riders from the Marketplace.

Then again, based on meta-criticism that's called out the game's apparent unresponsiveness, just about anything could serve as a demo for Sonic Free Riders. Flail your arms while watching your daytime soap operas, for example -- that should deliver roughly the same interactive experience.
