Today, we're officially declaring it an Xbox Live Marketplace Demo Extravaganza day, because we're seeing the release of not just one, but TWO super new video game demos to the XBLM. Like we said, it's a demo extravaganza!

First up is a new 1.25GB Sid Meier's Civilization Revolution demo, featuring both single and multiplayer play and enough turn based strategy to shake a stick at. And for those of you who didn't win early access last week, the new 1.5GB Battlefield: Bad Company single (slash) multiplayer demo is ready to be consumed by you, the masses. Hit up the XBLM, queue some demo deliciousness up for download and get your game on.
