Beyond the twenty trillion other games coming out weekly at this point in the year, you might be worried about how you'll fill your weekend? Maybe? Okay, okay -- for the one or two of you with some extra gaming time right now, several new demos have landed on Xbox Live Marketplace: Apache: Air Assault, Joy Ride (requires Kinect) and Rock Band 3.

Assuming your home entertainment center is equipped for maximum gameage -- by which we mean you have no less than three televisions and three Xbox 360s before you -- you can now experience what it's like to juggle being a rock star, a race car driver and a simulation helicopter pilot at the same time -- without having to commit to such an impossible lifestyle. Or you could play one demo at a time ... we guess ... but where's the fun in that?
