You can now download a demo for both ‘GR:AW 2′ (multi-player) and ‘Major Leage Baseball 2k7′ from the Marketplace.  Both are free but ‘MLB 2k7′ is only available to Gold members in the U.S., Mexico and Canada while ‘GR:AW 2′ is available to Gold members in all LIVE regions.

Remember most material that is available to Gold members first is usually available to SIlver members one week later.
