What are your niggling (or throbbing) misgivings with the timeline or characterisations in the Kaiserreich HOI2 mod?
For me, it's the depiction of Huey Long as a fascist instead of agrarian populist. Huey Long was a lot of things - but a man who turns to political violence to get his way was not one of them. Demagoguery, blackmail, bribery, the worst sort of character assassination, and bureaucratic harassment, sure, but I don't think there's the need to exaggerate. Everything he did, he justified in public as staving off revolution and political violence. He wanted to slash the defence budget so it could be diverted to his wealth redistribution programs. The man was a borderline pacifist and about as far from a racist as you can get in 1930s Louisiana. Yet the game reduces his movement to little more than a Neo-Confederate movement by any other name.
