Heinz-Fiction: Germany is pretty strict when it comes to swastikas in video games. We hat a change in law in 2018 where developers could apply for uncutted games at our national youth protection organisation, the USK. However Saboteur was released in 2009 and i cant imagine that the Developer applied for that, as they dont exist anymore. I cant imagine EA as the publisher would file an application as this game is old by now and commercially irrelevant. I couldnt find any information that the saboteur is now legal in germany. So ... why is that?
You might try asking in
the German-language general forum. I know there are some of your countrymen who hang around here that pay attention to this sort of thing, and would probably be able to point you toward the "why".
What I will say is that I haven't been able to find any evidence with about 10-15 minutes of searching that
The Saboteur was ever region-locked on GOG. Given that it was on EA's Origin platform before it was here, it's probably likely that they paid to get it off the Index at some point back then, and GOG simply benefited later, once it got released here.
(Also, remember that Pandemic Studios had become a subsidiary of EA by the time this game originally released; and even while the studio yet lived, wrangling with a nation's censorship board is exactly the sort of thing that would be a job for a AAA publisher, not its first-party-developer subsidiary.)
