I think that the points about buildings architecture and the proper nomenclature for the civilizations itself, while valid, are a bit nitpicky.
I do agree that the Native American civs could use some reworks. The awkward “Tribal Marketplace” situation is the first issue that comes to mind. I also would prefer the addition of proper temples to replace/complement the “Community Plazas”, at least for the Aztecs and the Incas. And I also would like to see more unique flair being given to each civ’s crops, I even made a post about it a few months ago.
