And then there is realistic violence to humans but ain't nobody gonna ban popular FPSes :-)
Apple banned Fortnite.
That's true, but it had nothing to do with violence.
Not because of violence btw.
You mean fearless bullet sponges that leak red liquid after health bar exhaustion and fall without screaming in pain, or for their lost friends, or without begging you to spare them with horrified eyes? It's less realistic than in hollywood movies. [Don't] watch real footage to compare. Realistic-enough violence games usually can't even make it to the market, except few nsfl/ryona self-publishing niches. Would you ever like to promote one to AAA-grade, honestly?
