And this also ignores the fact that some nations have to be sacrificed because they wouldn’t play significantly differently from others, or they overlap, or they’re historical offshoots for each other. This largely seems to have been ignored when it comes to europe (like I said, eurocentric), but you can see why they might do it in Mesopotamia, where Babylon and Assyria probably would be Scientific/Cultural Builder nations with a militaristic twist, or Mali and Songhai, where they both had nations that largely overlapped with focused in Gao and Timbuktu. And then, of course, Siam (specifically under Ramkhanhaeng, first king of Sukhothai), are a Khmer break-off state, historically.
