"The problem is that the North American civs were to fragmented and small to be any major factor. None of them really deserves to be in Civ on their own."
Since in Civ all civilizations start out equal, the actual world events are not a factor.
My Native American friend says one of the main reason the tribes were fragmented and small was because of diseases and better technology that the invading eurapeons possesed.
Honestly, he found your comment a bit racist.
Actual world events are a factor because the civs are taken from the actual world. (and not all civs start out equal... 18 civs start out as potential players and another 30-100 start out as barbarians, and the rest start out as names in city lists or out of the game altogether)
Unfortunately all the pre-Columbian US Natives (not North Americans because Aztecs made it in) fall into the same boat as the Bulgarians, the Turks, the Koreans, Carthaginians, Celts, Irish, Scottish, Autralians, Austrians, Texans, New Yorkers, Californians, Aryans, Polynesians, Maya, Portugese, and Corsicans of not having enough
1. customer base
and/or
2. Historical impact (as judged by the customer base)
to make it in to the top 18.
For reasons of geographical balance they will probably be in any expansion that adds more than say 4 civs, but if he wants to play cowboys and eurasians then he'll have to rename the Aztecs or Incas for now.
(and the fragmentation and smallness, although enhanced by the Europeans, predated them due to reasons such as geography totally separate from race.)
