Nah, i could call you 6 states alone in East Africa which lasted for around 1000 years.
Well Makuria or Ethiopia at that time were no bigger then France or the Roman empire, same counts for Ghana. The first true super empires were Mali and Kanem.
Isn't Koumbi Saleh the capital of Ghana? Whatever, i am interested in how these units will look like.
Even if Makuria ever would have been a vasall (Which it wasnt) the map still stretches to the Alodian capital Soba. If i were a developer i would rather cut the map under Egypt and give the free regions to the Fatimids rather then making such an unhistorical decision.
Well if you think that these hills do justice to over 2000 m high mountains, often referred as the roof of Africa...
