I would add an extra leader choice for all the nations (minus the Air Nomads), but I don't know how to. The barbs expand pretty quickly, and could almost be considered a fifth civilization in their own rightĮach nation consists of a leader from the show. There is also a Barbarian city (called Merchant's Pier) on the west coast of the eastern Earth Kingdom Continent. Balance-wise, I find that the game favors the Earth Kingdom (they got the HUGE continent in the east) and playing as the Water Nation can be a challenge (you start in the North Pole, with nothing but Ice tiles!). I've tried my best to decorate the areas explored in the show, as well as those not shown. This is my first map that I've ever created in Civilizations 4.
