Microsoft has a great deal going right now through its Games on Demand service: grab The Complete Edition of Civ IV for a measly $9.99.

Regularly $39.99, the set is 75 percent off and includes the original Civilization IV, the Warlords and Beyond the Sword expansions, and Sid Meier's Colonization.

The deal ends on Westatic.aayyy.com/topic/dn/esday, September 1, so get to getting it while it's cheap.

Thanks, Joystiq.
