Yeah, that's true. It's basically a rule of the Internet, any popular enough vaguely political game will eventually have good leftist mods. Whether the timeline and mechanics plausibly permit socialism to exist or not. There's also the Paradox rule, basically any game by them either has a Cold War setting shift mod already or the creation of one is inevitable. But I've personally never sought those out or tried one, I don't need or want a Cold War strategy game - being housemates with a washed up Cold Warrior who still blames Russia for all his problems, and knows I'm a big fan of the Bolsheviks and calls me a "pinko" and a "commie", is enough Cold War action for me.
