Stellaris is, from what I hear, a rather champ 4X sci-fi strategy game, pooling lessons from Game of Thrones simulator Crusader Kings II and nation-builder Europa Universalis IV. With the vastness of galaxies as its canvas, the cultural milieux range from frog-people to sentient AI machines. Bipedal meatbags feature as well, but as it turns out, they just had too much variety for some.
One user, originally going by Lord Xel and now Progeny of Europe (promising start), posted a mod entitled “European Phenotype and Names Only (White Humans)”, which replaced all the human in-game portraits to be what I assume would be an acceptable pallor to the mod’s creator. It hung around a bit until, according to Paradox, some additional edits to the description (the statement “No multiculturalism here!” highlighted as particularly egregious) and user comments on the mod pushed it into unacceptable territory.
