Changing the Lakota campaign was the wrong decision, and I wrote a short paragraph about why.

I think that the original campaign was a really good representation of a regrettable moment in US history, which was the Black Hills Gold Rush, where the main character goes from fighting Lakota to seeing that he was fighting for the wrong side and instead fights for the Lakota. Holmes and Custer are both cartoony and unrealistic characters in the remake, and in the original, they were both nuanced villains which is the more honest portrayal. I think the original campaign did a good job telling Chayton Black's narrative in an honest and believable way that also manages to honestly portray the Black Hills Gold Rush as a regrettable moment in US history.
