Vietnam should be the final G&K civ....
There is no new Asian civ announced, they have a history (definitely of resistance), they are a minor nation in vanilla, and they would bring a lot to thegame.
They would easily be a defensive military nation so their abilities should be defensive...such as longer rebellion time for occupiers, cltural defense on their borders, guerilla UU's....
Leaders should be either Lady Trieu, King Ngo, or Ho Chi Minh.
Interesting...I didn't realize there were no Asian civs listed. Vietnam doesn't seem likely to me though. Majapahut is oceanic and is a likely contender though.
Hanoi has been seen as a city state, so no Vietnam unfortunately
Vietnam may never have been expansive, but they either defeated other powers or when occupied...made life a living hell for them.
They even defeated the Mongols.
Technically, and according to their city style, the Huns are an Asian Civ. Vietnam would be interesting, but again, we've seen Hanoi as a CS in the new screen shots, so it won't be in this iteration.
