I guess? I honestly had never heard of the "88" terminology, I guess I just don't follow neo-Nazi nonsense that closely. Maybe I'd respond by making the protagonist Jewish or something in a minor content update, just to mess with people.
This whole "cancelling" culture is absolutely stupid. Neo-Nazis don't own numbers, hand symbols, or anything else, so I wouldn't give in to that nonsense. Then again, I'm not trying to live off making video games, and if I ever did release any (and I hope to), it'll be as a hobby and not as a job.
