Damn, and I thought my
country's bureaucracy was glacially slow. Why did they ban DOOM 2? Was it because of the secret Wolfenstein 3d level?
Technically it wasn't banned, it was just not legal to sell to minors or in places that cater to minors.
Wolf 3D was never banned in Germany, but the censors did require a special version be released for the market which removed the swastikas and some other things like blood IIRC.
I think you're thinking of the SNES version that removed the swastikas and Hitler and changed the dogs to giant rats and blood was made to look like water. I don't believe the PC game underwent this change and was therefore banned for the swastikas and Hitler,
Not only was Wolf3D banned, but it was also confiscated, from what I've read.
"Due to the game content, this game may not be ordered by residents of Germany."
