The german Government does, unfortunately.

We have several youth protection mechanisms in place. For example, you cannot buy a Game which is rated "18" in Store unless you can prove that you're 18 years or older.
18 is the highest Rating for any Media here, because if you're 18 years old, you're legally considered "Adult" and can do whatever adults are allowed to do.

However, the Government talks about censoring Games to some extent. We had several pupils run Amok in their schools in the past and in the government they believe that Shooter Games, where you shoot at stuff that looks like real people, e.g. Counterstrike, Grand Theft Auto and the like, have a big share of the blame.
Thats because these boys had those games on their computers before they decided it would be a great idea to go to school and kill as many people as possible.

Because they killed people and had these games on their computers, many People in the Government think, that if you play those games, you're more likely to become a murderer than if you play, lets say, soccer games.

They even go this far to say that playing Shooters would train you to use a gun "professionally".
Now, everybody who has ever shot a gun in real life knows, that this is bull.

Now, they are every now and then talking about banning Shooting games completely. Even if they are rated "18" and are not legally available to minors, they think that it would be best to even take them away from the adults and ban them, so that the production and possession of those games becomes a punishable act.
More than one politician compared those games to child pornography and suggested that they should be treated alike.

The same is with Swastikas. The Swastika is a banned Symbol in Germany and so, games are not allowed to have them.
Under the premise of this Thread, Mods which have the Swastika would be illegal.

Every time the Media wants to show the bad, bad influence that Computer Games have on our children, they show a Scene of Counterstrike, Grand Theft Auto or a WW2-Game Mod which has a Swastika in it, suppressing the fact that these Games are not available for minors or, in case of the Swastika, the Game was modded and is not originally available with it.

Youth protection is important, but what german politicians make of it is a bad joke.
