Why are people so touchy about symbols like that? Only the people who watch videos or play the game will see it, and since it's a South Park game I think people know what they're getting into, same with other games.
It's understandable that Germany and Austria are rather picky about that part of their history and I kind of support that free speech is limited in this area.
Imho the specific law in Germany isn't well written.
In general the usage of Nazy-symbols is illegal with a few exceptions:
"(3) Subsection (1) shall not be applicable if the means of propaganda or the act serves to further civil enlightenment, to avert unconstitutional aims, to promote art or science, research or teaching, reporting about current historical events or similar purposes. […]"Movies for example are considered a form of art so you can show them in them but games aren't considered art by a court yet.
Many experts think that if you would go to court you would win but the problem is that nobody does because they understandably fear the bad PR from such a move (Headline: "Ubisoft wants your kids to play Nazi Games").
Austrian law is quite similar but imho better written when it comes to exceptions:
Usage of Nazi symbols is allowed in print, pictures, stage production, films or exhibitions as long as it doesn't support that body of thought.
That law is from 1960 so it doesn't account for modern media but I'm pretty sure it would also apply for games.
ahh I didn't know that... and yeah Ubi is a pretty all-round awful company. That said it's still pretty easy to get a US version (like I did) and play it with no troubles
Maybe on consoles but on PC you would have to use VPN/Proxy and risk your Steam account. So I would rather buy the game and play a "illegally downloaded" version.
