Stellaris, a grand strategy game set in space, has characters who come in a variety of species and races. Naturally, someone made a mod to turn all the humans white. The mod, "European Phenotype and Names Only", makes it so your Stellaris rulers and heirs will all be white people with European names, which is why publisher Paradox pulled it from Steam. Said Paradox in a statement to Eurogamer:
"We shipped the game originally with an accurate representation of humans, that is to say diverse in both ethnicity and personality. We embrace the idea that players mod the game to best represent how they want to play, we do NOT however wish to enable discriminatory practices. We appreciate any inappropriate mods being brought to our attention and will take them down where necessary, we also encourage players to make use of the flagging function provided by Valve where needed."
People who don't want other races in their Stellaris playthroughs can still get the mod on ModDB. The first comment there may not surprise you:
