It's an epic gamer challenge, but one that comes up against being enough of a spreadsheet nerd to learn a game like that. I've had Papal States runs to try to make the Kingdom of Heaven for the novelty of it. It sucks. Everyone hates the church and I play whack-a-mole for centuries while sabotaging my own shitty economy and going to war over minor countries. Playing as the American Confederates means like 30%+ of your population is permanently radical and unable to do skilled labor, your standard-of-living is severely limited, and every country without slavery has a permanent war justification against you. It empowers your landowners who steal all the surplus for themselves. HOI4 Nazis can cheese their way to an early war victory, but it's the worst power bloc in terms of allies and doing fascist things tanks your stability. Colonialism across all the games is only profitable in very limited contexts, but going for those choice territories means perpetual war and overextension while not building up your core. Fascism isn't fun in their games and it punishes you in ways that make it super frustrating to play. Line permanently go down in a game where the entire loop and dopamine source is line go up.
