The game formerly known as CIvilization: Network - now more appropriately titled Civ World - is coming later this year. But if you're lucky, you can play it this month.
While the game's open beta won't be taking place until around June, beginning January 12 select alpha testers will be let in the front gates to test and play the game.
Those who do get in should know that for the first time we now have an idea of how Civilization will be played over Facebook; it'll be divided into finite games that have a beginning and end (as opposed to an endless struggle), with winners declared at the end of each "era" and then at the end of the game itself.
