Age of Empires 3: The WarChiefs — 2 North American peoples are now available: Iroquois, Sioux and 1 Central American people: Aztecs. When playing as any of them, you start with 5 workers. Moreover, Indian workers can build city councils (for Europeans, this action is available only to the researcher). Each of their buildings has a special improvement (“big button”), offering bonuses in the form of supplies of units or resources. Another feature of all three powers is that from the very beginning of the game you can see all the trading posts on the map.
