Lots of stuff deemed ‘Unsuitable’ is banned in Germany.
Whether it be history, games, TV, anything that does not conform… They will ban it.
I feel sorry for any Germans who can’t play games, because the government bans them. 
(C&C Generals zero hour is a pretty notorious one. They let the base game in, but not the expansion? They said it would cause mental harm do to the game being to closely related to real life happenings… My C&C gaming buddy over there is still sad about it.)
But that’s just my 2 cents of rambling!
