I think it’s because the Nazis while the enemy, are still portrayed as powerful and intelligent. I mean, they make a mecha-Hitler and all the bosses are Arnold big bodybuilders. I think Jojo Rabbit took a great approach to Nazis, show how evil their ideology is while taking the absolute piss out of them and making them look like laughingstocks. That level of nuance was difficult with the technology they were working with though, and wolf3d really was a revolution in itself.
