Yes, but I would say that Ethiopian architecture stands out quite a bit from the Middle Eastern. Somali, Swahili and even Nubian architecture have more similarities with the Saracen set: square buildings, flat roofs, arches, vaults, probably due to the similar climate and/or Islamic influence (the differences being that Nubians built with bricks and Swahili and Somalis built with coral stone).
Zeila and Mogadishu, Somalia:

The Ethiopians are in a tricky situation because they have such a distinct architecture and not shared with anyone else (with unique features like recessed walls, “monkey heads” — wooden beams that cross the entire building, and the rock-hewn churches). Since I don’t think the devs want to repeat the Indians situation, I can only imagine them putting the architecture of each people divided into each age.
And in a way, the same “challenge” of architectures that are too distinct from each other applies to other regions of Africa, as you can see below:
Benin/Yoruba:
There are no exact images or photos of the architecture of the Kingdom of Kongo, only descriptions. But here are some houses from Colonial Angola and some analogues from Luba people:
Finally, Zimbabwe:
