Technicly, if trotsky successfully executes the coup in the soviet union because Stalin didnt purge they should be facist, rather than still being communist as they are in HoI IV (again at the time of the stream), but i am not familiar with trotksy's party or ideology.
If we are looking at ideologies, Would make more sense to make Stalin fascist than Trotsky. Basically Trotsky was Lenins golden boy and Stalin power-played to install himself as leader of the USSR by playing the other politburo members against the favourite then moving himself into play before they realised what happened.
Stalin then started his cult of personality and started to implement all the totalitarian ideals which made him just like the fascists. So him and Hitler were brothers from another mother.
Trotsky was the guy who led the revolution in Russia whilst Lenin was in Switzerland, giving Lenin the power when he got there.
Yeah, I disagree with him being fascist, makes no sense.
Would have liked to see a Communist Russia under Trotsky as a game to pull off, but the idea that he would be in the same boat with people ideologically different makes the idea less appealing. Would rather have him heading the democracy faction, it is closer ideologically. I am guessing HoI doesn't have 3's multiparty.
