Take-Two has said that the beta for Sid Meier's Civilization Network isn't expected to hit until sometime in June.
Back in October creator Sid Meier revealed, "I wanted to let you know we'll soon be looking for beta testers to help us develop a unique new way to play Civilization." That was October. 2009. The beta isn't now expected until July 2010, eight months after the announcement of 'soon'.
Civilization Network will allow you to join up with friends to create the world's most powerful, richest, smartest, or "just plain coolest civilization." Most importantly though, it'll be free to play.
You can coordinate strategies, share technology, lobby friends to form new governments, manage and grow your cities, spy on your enemies... all the things that made Civ the gaming form of crack in the first place.
