I'm indifferent to Native American civs. They'd be relegated to early game UBs and UUs (Which we have a lot of already) and none of the north American natives have ever impressed me historically. They commanded tiny populations, were technologically hopeless, and their greatest achievements range from "Briefly prolonged sovereignty" (Sioux) to "Building on a cliff face" (Pueblo).
I think that both in terms of theme and gameplay, the Iroquois cover everything the north American natives have to offer.
What can you expect from the people who took another 1,500 years to even consider the #0 as a legitimate number for mathematics
. Appears people are constantly confused with population, I won't get into a large spiel here but a few small things...
===============================
Native Civilizations often exceeded the populations of European civs by large amounts. Europeans were largely unclean, carried disease constantly, had malnourished peasants, an average life expectancy of about 32 until the late 1800s. Compare that to the largest Native Civilizations who invented soaps, antibacterial medicines, reaching populations in the tens of thousands per city when Europeans would only have a few thousand per city
Some of the largest metropolises in the world were native. The city of El Mirador is larger than Los Angeles even is today and it existed in 1,000 B.C.E. to 100 A.D. - And thats only considering the stone foundations of the city, not even the wooden houses of the peasants that have since long decayed.
We have cities like Teotihuacan, Tiwanaku, El Mirador, Tikal, etc. When the Spanish arrived in Mesoamerica - they couldn't believe that they saw a city at every hill and river, or what looked to be a massive city to them in their accounts. A decent size although limited city like Tenochtitlan impressed them so much that they thought they were walking in a dream and couldn't imagine Spain like that - much less Europe
