I agree. While I’m grateful they changed the name to Lakota, considering the inaccuracies of the word Sioux, that solved nothing about the actual inaccuracies of the in-game representation.
The Lakota in this game are less accurate than the Indians are, and if you’ve seen the multiple threads concerning the Indians, well… you get an idea of how badly the Lakota are portrayed, and I know the Aztecs and Haudenosaunee are on a similar level.
