To celebrate the 5th anniversary of the Xbox Live service, Microsoft is giving away a lot of free stuff on XBL this week. The best of the bunch is the XBLA game "Carcasonne", an awesome casual strategy board game. Normally its $10, but you can download the full game for free starting on the 15th and going through the 16th. This will also include the "Rivers I" expansion for the game as well, and the game supports up to 5 players simultaneous.
Its one of my favorite XBLA games, and now that its free, no reason to not check it out!
