Absolutely
It looks more than great:
North (12): Iroquois, Hurons, Apache, Navajo, Sioux, Cherokee, Comanche, Shoshone/Ute, Inuit, Algonquian, Crow/Apsáalooke, Blackfoot/Niitsítapi
Central + Caribbean (6+2): Aztec, Maya, Zapotec, Mixtec, Guaymi, Tarascans/Purépecha + Arawak, Carib
South (10): Inca, Tupi, Mapuche, Tehuelche, Shuar/Jivaro, Guarani, Muisca/Chibcha, Omagua/Cambeba, Machiparo, Toromona
However, I wouldn't say certainly no more civs if I were you
What if a perfect LH candidate shows up/is made (in a couple months) for Cree or Seminole for example?
There are still a couple civs (actually only a few left
) worthy to be included
