So i was looking at an Americentric map last night, and it occured to me that Alt history generally only focuses on very small changes that are at least familiar to the reader. I understand why, but i feel as though that places topics into a pretty narrow category. My thinking is this: We have two continents that existed outside the knowledge of the rest of the world for almost the entirety of human history. Really all it took was having sea faring nations cut off from the spice trade in order to get a permanent discovery. Now what im curious about is: what are some completely unexplored alternative fates for north and south America? Could the present day see some type of continent wide DMZ that runs the length of the Rocky Mountains or the Mississippi, with the sides controlled by pan-Asian and pan-European states? What about a surviving remnent of the Roman empire, or Carthage? A world where the Incans or the Aztecs had created a loose confederation that spanned their respective continents? You do see it from time to time, such as Islam spreading to the new world, or native Americans getting a better shot, but generally its confined to "Europe discovers entire continent, proceeds to colonize." What are some things that, with a POD perhaps in ancient Egypt, that give a completely different fate for to the Americas?
(And yes, i recognize that diseases and and plunder are likely going to happen. But what happened OTL, the gradual breakaway of Europeanish countries, doesn't have to be the case.)
