i doubt it, there are quite a few low-quality asset-flip games build around politically-incorrect memes on steam.
Even if there are dark games, they are meant to be parody/satire. Certainly not done in the same spirit what the white house is doing here.
The games that it gates are probably about 95% porn and only about 5% racist but the racist games are there ("tyrone vs cops VR", "cuck simulator", "goyslop", etc). I will admit some of them do at least look funny based on how they present themselves in the trailer but they're all obviously low-quality asset-flips that would've been considered slop even before the age of modern AI.
