Am I the only one who questions why ALL tribes have an infinite pool of warriors? Why cant WE find their area?
Natives gon' native. And technically you can see where they live on the world map.
But for consistency sake let's assume the natives originated from a stock of settlers who went native, who were genetically engineered/predisposed (https://docs.google.com/document/d/1pIZyKif0bFbBWten4drrm7kfSSfvBoJPgG9-ywfN8j8/pub) to rapid expansion.
They downloaded the Offspring and Genetic Enhancement mod, obviously, and live on a 450x450 map tile so they can replace their numbers quickly.
And apparently have a breeding cycle of ~3 days.
They probably came off some kind cloning facilities that were never turned off.

I imagine it's more like in real life where you'd have little tribal bands roaming around, all having some common culture or sense of duty to rally in defense of each other. Think "warpath".
What I'm saying is that the entire world is likely full of natives, but they live dispersed over the entirety of the world. Some are part of tribal confederations, and it's them who send the raids.
What that model doesn't explain is why they don't show up with 150.000+ men, like a certain Germanic confederation did back in 113 BC. But presumably we, uh, ahem, *they* had a much higher population density, which is why w... they decided to start a horde and head south-west.
They way I look at it they came to steal my trenchcoats and cowboy hats, they end up becoming more coats&hats, their neighbours show up, even more coats&hats, even more tribals... It's a vicious circle and I blame the toxic cowboy culture for it! :P
