For instance, the Civ games are basically Whig History: The Game, presenting liberal capitalism as the ideal end point for all societies. It even includes uncivilized "barbarian tribes" whose sole purpose is to be exterminated so you can take their land for the glory of capitalism.
I never really analyzed Paradox games all that much, but I suppose their gameplay mechanics are inherently ideological though someone else probably has a better way of explaining.
But, in HOI4, I remember someone asking why civilian casualties aren't simulated and a dev said that purges, genocides, civilian casualties, etc. aren't going to be included and never will. But then they added The Great Purge as a mechanic for the USSR as well as famines. Obviously I don't support a Holocaust mechanic or anything like that, but these dweebs often say that the USSR is as bad or even worse than the Nazis, and yet the supposed deaths and 'genocides' are treated as a fun gameplay mechanic for you to ponder about whereas Germany's crimes are too evil to talk about. They don't even respect the "victims" of communism as much as they say they do lol.
And apparently, the Great Purge is the correct choice to make in the game because otherwise you're betrayed later on in the game.
They also only acknowledge high ranking military personnel as victims, with no event for forced deportations and migrations which would and IRL did lower manpower. Also when talking about HOI4 not having a reference to the concentration camps, tvtropes in particular will ALWAYS mention gulags in the same sentence, as if that is even remotely the same shit
Yeah there's really no good options for a game where you can control nazi germany to have a "do the holocaust" button or no. There's very bad things about both. Either you are whitewashing Nazis or pandering to fascists.
Someone else once said that a decent way to handle it might be to have a "concentration camp liberated" event that fires when you take certain provinces while fighting Germany and I think there's some merit to that
