2 Mesoamerican civs? Hardly better represented than Europe lol

Lets put it this way, Central America is large landmass wise comparative to a continent like Europe(bigger on definitions of extents). For Mesoamerica there are several major empires the Toltec [The Persians of the New World], Teotihuacan [The Assyrians of the New World], the Zapotecs [The Hittites of the new World], the Olmec comparatively can be said to be
similar to the Sumerians of the Old World
That's ignoring the great South American Empires too. The 3 hundred year war between the Huari and Tiwanaku empires and subsequent "cold war", that shaped centuries of history. The Chachapoya who controlled trade between South America and the rest of the world, controlling the gateway between the Amazons, the Panama Isthmus, and with substantial proof that they traded even with Polynesian islands [As seen by various Pacific plants in the tombs of royals], and various other South American civs that offer tons in fascinating gameplay
You are magnifying everything.
For every 3 civilizations you say that are missing in America I can bring up 6 that are missing in Europe and Asia.
So what if some are missing? You can't include every civilization. Just the very dominant ones.
And these are the Aztecs, the Maya and the Inca.
You can rightfully say that the Toltec or the Huari were indeed important and influential, but we don't have enough information about them and there are no known leaders of them, so they are in a lower priority.
I think that civilizations like Afghans, Kushans, Tamils, Burmese, Khmers, Gokturks, Hittites, Seljuqs, Xiongnu, Tibetans, Vietnamese, Bulgarians, Venetians, Congolese, or Malagasy are much more important AND documented, and also can represented a not fully represented area (except the Khmers and Venetians), those are in a higher priority to me than some more Mesoamericans.
Adding more of those Mesoamericans that you mentioned are similar to adding the Akkadians or Elam to the current game - they were important, but people will rightfully say - "there are greater empires for their spot, their area and their culture is already fully represented."
However I do support adding more CS like Teotihuacan (which is a classic CS).
This IS a US-Centric game Absolution no matter how much you hate it (which seems an awful lot). It means we will get an America-esique focus, so when I point out what the Iroquois did, yes it did make them more significant than many other tribes here in the US. It certainly didn't make them people stuck in the mud as you and others have said
We have had 4 different civs from Mesopotamia. Comparatively we only have 2 from Mesoamerica which is nearly as big as Europe. And only 1 from the west of South America. Not that I expect either of course, partly because of Euro-Centrism and partly because many of these civs are less known in the US. From gameplay perspectives they can do plenty with other civs too even possibly lesser ones like the Sioux if they do include them.
Please, don't compare Mesopotamia to Mesoamerica.
