Well, I won't touch the essay American Kroger - I'm sure it was linked here many times over. Yet I thought it was interesting what he brought up. Basically Dan Houser wanted to some of the politics of the 21st Century to the late 19th Century. If you think about it, Arthur is at best, a late 20th Century man (say, 1980s) in 1899. If you are honest with yourself and you want to tell a story, you got to show what happened in a specific time period, and not beat around the bush.
Now, I think M.A.F.I.A. 3 did that to show "how horrible", and perhaps this came out as a good way to show how things were in fact. The Houser brothers should have shown how the Reconstruction took its toll in the Southeast and how they were going through the Gilded Age.
But alas.
