I wouldn't call it fairly recent when the generation who experienced it is dying out and the necessary premises for a revival of economic or racial anti-semitism in german society today are non-existent
This may sound shocking to you but militarism and chauvinist propaganda was normal during the first half of the 20th century and before, the Sonderweg theory has been debunked since Germany did not differ from most european nations to such an extent to conclude that it would have followed a unique path.

It depends on the game how disruptive the censorship is, sure if it's just a removal of a few swastikas it isn't painful and can be changed with a simple uncut patch/graphic mod but when the whole lore is completely changed to get rid of any hint to Nazism or when in a strategy game like Hearts of Iron all Nazi ministers are replaced with 'black shadow' it changes the game beyond recognition in an awful way.

But the point is that allowing Nazism in videogames isn't the same as allowing it to be glorified, and there is hardly any game which does such a thing and they can still be outlawed.
