Weird ...
I sometimes watch South Park on Comedy Central Germany, which is also on the cable network in Austria and Switzerland.
And I'm pretty sure I once watched an episode in which Cartman dressed up as Hitler with a swastika badge. And that was not censored.
He also attacks Kyle frequently as being a "vile Jew" or something, also not censored on the Berlin-based CC-Germany ...
IIRC, television is considered art under the German law and thus exempt, while video games are not.
The German/Austrian law is annoying and dumb, it always makes Paradox censor the historical WW2 game Hearts of Iron, from using historical German Nazi symbols, that are.. historical. I get the point of the law in say the 1950s, as part of Denazification, but Nazism is not a widely celebrated philosophy on the verge of a comeback in those countries in the 2000s, times have changed.
