Yes, west Africa, the place that at one point had the most gold on earth, was truly a collection of loin clothe wearing Neolithic tribesmen. They had no advanced society, oh no not at all. Not a single city ever attested to in history
I swear it's like people think all of Africa was the interior Congolese rain forest or something. The Malian and Songhai states were large, wealthy, and they certainly we're using metal tools plenty. They were much more advanced militarily than the Native Americans were. Europeans still took advantage of a period of instability to conquer then, burn a bunch of their cities, and reduce them to a far more agrarian state
America would look, charitably, like Asia does not and uncharitably like how Africa does now. The euros are still gonna go colonial, but there will be a native population about to care about their own rights denied to them by dint of race
