Benelovent Chieftain of the Ursu Kingdom
18 was the total originaly slated for launch. But Beach and others have suggested adjustments will be made on the game before the release date. Meaning not all is set in stone maybe. Perhaps they will make room for 4 additional Civs to bring it to 22.
Source?
They seemed to have confirmed that the game will ship with 18 civs one way or another. Possibly 19 depending on where the Aztecs fall.
