Steam has listed Civ IV and it's expansions in The Complete Edition bundle that carries all four games at a cheaper price.
Additionally, Steam has taken an extra 10% off through this week, with the discount applying to both the bundle and individual game purchases.
Several Sid Meier's Civilization games, including Sid Meier's Civilization III: Complete (dropping to $0.99), Sid Meiers Civilization IV: The Complete Edition ($4.99) and Sid Meier's Civilization V: The Complete Edition ($12.49).
The new Humble Bundle is here featuring plenty of Firaxis Games classics, ranging the gambit from XCOM to Sid Meier’s Civilization. The charity of choice is Action Against Hunger.
For In Conversation #2, Mark and Adele from PN2 play a little Civilization IV as a tribute to Leonard Nimoy, who lent his voice to the game all those years ago. We also discuss The Legend of Zelda: Majora's Mask, bushfires (because we've got those in Australia ... a lot), and THAT dress. Yup, you know the one.
Anybody that needs a fantastic strategy game for their computer, get this game now. Great replay value, countless mods and a game that will easily play on most computers that have come out in the last 6 years.
like Agent VX said, this game is definitely worth buying
