Civilization World, the Facebook incarnation of the epic strategy series, is expected to launch this summer. A recent piece by CNN, in which Firaxis emperor Sid Meier called Civ World "the most dramatic stretch" the series has seen so far, as Meier expressed a typical Civ multiplayer game can easily span 12 or more continuous hours, but the Facebook version can start and stop over days and weeks.

The last major "stretch" for Civilization -- if you don't consider hex-based boards totally crazy -- was the console-based Civilization Revolution. Despite taking the core elements of Civ and doing a great job of bringing it to consoles, it apparently wasn't good enough for a sequel.
