Two single player campaigns provide plenty of strategic practices, but it's the online component that really makes The WarChiefs shine as a few new features make the old feel new again.
Players who can run the map well will like the Trade Monopoly win condition which allows you to attempt a victory by holding more than half of the trading posts on a map. Another new twist is the Revolution option. This can only be done by the European powers, but it allows a civilization to instantly turn military. All setters turn to militia, only military units can be sent from the home city and it is impossible to gather resources. Done at the right time, revolution can quickly change a losing position into a winning one.
