@Umlaut unless the game is made by people aware of the system they live under and are against it, it will have at least aspects of it baked in.
warcraft 3 is pretty bad about this; mass effect is extremely obvious.
every other scientist is a nigger in half-life despite that being extremely unlikely even now, if they are doing actual research. it would have been more likely they would be some kind of east asian (if they MUST have non-Whites).
age of empires makes all civs equally capable against each other, and some of the civs were barely civilizations in real life (re: the sub-saharan african civs)
deus ex is a game I still like mechanically and some of its story but it is schizo boomer conspiracy theorist bait and is not against transhumanism in its premise either.
I only played fallout 3 and new vegas but all the vaults are mixes of different races and yet they persist for long periods of time without formal segregation and no rapes/miscegenation.. and everyone's equally capable. this is excusable for the player character because you are fundamentally the chosen one, but not everyone else.
the map painter games from paradox will let you get away with some "illiberal" things but notably, and I recall this, there's no way to back the Klan in America and actually just be a pro-White country.. the only option is to destroy the klan to remove the threat to your power.
my guilty pleasure, Stellaris, without mods, has men and women equally capable and while warcrimes are easy the three paths that are heavily pushed on the player as ascension perks/paths all lead toward heavy modification of your species (psionic making everyone conduits of demons, machine ascension killing and uploading everyone into machine chasses (with its lesser brother "cybernetics" that still heavily, recreationally, modifies your species), and genetic re-engineering to completely remake your species). xenophilic empires do not collapse if a player is running it and knows what they're doing and multiple species can be together on one planet and there are .. no problems unless you specifically make there be problems with certain traits for certain species.
the rest I don't have much of an opinion on because I didn't play them much.
