Sometimes you can finish in the top twenty and still have a community disappointed with your performance. This happened to Genghis Khan of all people, whose traditionally aggressive civ did not even begin to live up to expectations. Part of this was their bias for Keshigs leaving them devoid of melee units, but it was mainly just an uncharacteristic lack of aggression. If only this game had had city states, we may have seen more violence.
