The crown jewel of this week's bargain crown is Steam's offer of Empire: Total War for a mere $25, down from $50--just in time for the sizeable update 1.3 arriving Monday. Also available with 50% off is the $35 Empire: Total War Special Forces Edition.

Steam also celebrates its addition of sixteen titles from war-happy NovaLogic by offering 10% off them all, including the Delta Force and Joint Operations games.

Good Old Games is offering 25% off shooter Painkiller Black Edition, down to a trifling $7.49--the discount will appear when you go to the checkout.

Joining the library expansion fun, Impulse still offers 10% off Ubisoft additions Far Cry 2, Assassin's Creed and Heroes of Might and Magic V - Tribes of the East.
