Aztec, Iroquois, and Lakota were replaced in the Warchiefs expansion, so it would make sense to replace the Inca as well. I think their replacement was the Mapuche but that only really makes sense in the south. Muisca would make more sense as a replacement in the northern Andes.
it would, there were different tribes of Iroquois back then and even in the campaigns you had to face enemy Iroquois
Please, stop repeating it! The old developer made the mistake of making this replaced. It would be make to do, as I described in the previous post
“If there is no Aztecs civ in any players, it may well be random map generated the Aztecs natives.” etc
