^ I agree 100% it seems that most people just want endless lists of evidence of these nation's technology. Maybe Paradox making their tech rate at 40% now instead of 10% is a sign that they might be looking a little more favorably upon the Native Americans. I've put my ideas out lots of times I'm wondering if other people have "simple" to implement ideas that would make the gameplay more accurate and more fun without overhauling an entire part of the game. I kept mine to a simple add an event chain showing disease devastation, instability, and then recovery after contact and maybe a decision for the Inca showing their administrative ability (increase efficiency maybe?), maybe a decision for the Meso American states we could have it be based off the flower wars and be + army tradition yearly because they're always fighting ceremonially anyway. For the USA/Canada natives I'd be kinda stumped they were very adaptable and at the same time managed to remain stable so maybe a tiny 1% tech boost and 3% stability cost modifier? My only other thing is the accurate boundaries and manpower/tax base. I might be off by 1-2 provinces but basically here is a map where purple = what the in game empire is and I added in red what they should also have (you can debate the northern one the southern half of it was Inca the natives spoke the Inca language of Quechua so for me that justifies it).

The total population of the Inca region if you take the starting populations of each province is 50,024 (yes I've counted the starting pop of every Inca core province the dates for the starting pops rage from 1399 to 1472) the total population of the Inca Empire at 1438 is an estimated 12-32 million.
Since Europa only depicts urban populations his would mean that 0.004% of the population lived in urban areas. Which is hopelessly wrong. Keep in mind that calculation is using one of the LOWEST possible estimates of Inca population. The Inca had an orderly system of provinces where each province had 200,000-400,000 people. there were 20 provinces each with lets say 12 million people. In game there are about 30 provinces in the Inca Empire that would make it pretty close to the historical number of inca provinces which means each province would have a population of 150k-300k. The estimate of population in 1571 (after the last remnants of the Inca were finally defeated) was 6 million. Again our in game estimate of 50,000 living in urban areas compared to a population of 6 million is still wrong for a nation built much like Japan with the population concentrated in fertile valleys since most of the terrain is jungle or desert or mountain.
If you feel like looking at my sources most aren't on the internet really but here's a list

Inca are the biggest problem with land/tax base/manpower the other nations are far more accurate with the exception of Meso America not being city states but I feel like thats a bit much to ask for.
*edit* For this giant geographical area and lets take the after disease population of 6 million. The in game player gets a standing army of 20-30k with FULL Quantity sliders. The population of Castile in 1516 was 4.5 million and I think everyone here has played enough EU3 games to know that Castile can raise an army of 50k with that. I know this is a slippery slope because it would seem like I'm asking for the Inca to get an army of like 80,000 which to be honest I think would be accurate because that was the size of the royal army at the end of the Inca Civil War BUT I think it would be much harder to balance the game so that Castile almost always wins. The Event chain I mentioned above would have to be truly devastating and cut the army in half for say 30 years or something very drastic like that.
