If you use one of those new fangled "cloud gaming services" - more specifically, if you use OnLive, they've got a great deal going on if you want to play the new Civilization V expansion pack.  If you purchased Civilization V: Gods and Kings for the normal price of $30, they'll throw in the base game (which is required) for free.

ike every Civ game before it, Civilization V has gotten an expansion pack that tightens and balances gameplay, adds new units and features, and makes the game even more addictive. With several new core systems added, new scenarios, new leaders, and new units there's plenty of content here for an expansion in the age of DLC. Let's see what Civilization V: Gods and Kings has to offer.

After a long time waiting, Civilization V fans will soon have their patience rewarded in the form of the “Gods & Kings” expansion scheduled for release this Spring.
