First of all I am not an anglo-saxon protestant (though I am white) so I do object that generalized racist remark.
I didn't say that the people of Central Asia did not have some great civilizations. I am saying that the MONGOLS as a tribe, in the period of time which MOST people suggest they should be in the game (In the times of Ghengis and Kubilai), were still not civilized, and I do not use the terms non-civilized as meaning barbaric. Just cause you don't understand the literal meaning of civilization, you don't have to lash out at me. During the time of G and K, the kingdoms "created by the Mongols" had not yet begun becoming civilized (building cities, although they of course were using farming). During the time frame which MOST PEOPLE seem to be recognizing as the time which the Mongols should be in the game, they were still pillaging and had not yet begun to integrate much into the local civilizations, but rather just rule them.
CIVILIZED DOES NOT EQUAL GOOD
UN-CIVILIZED DOES NOT EQUAL BAD
I am not being racist towards the Mongols
On the other hand, if they were to make a civ that represented all the people of Central Asia, then they SHOULD be in the game. However there were so many different non-Mongol tribes that were powerful as civilizations that it would not be accurate to label the civilization as Mongols, as they were only in control for a brief, yet significant period of time. After all you say that the Mongols moved in and had a significant impact on the local blood lines, well there were other tribes that moved around and had signifcant impacts on other tribes (including the Mongols) as well. The whole area is a giant melting pot of people, and it is not fair, in fact if might even be RACIST, to label them all as Mongols. It is similar to labelling most white North Americans as WASPS.
