DanTheKraut: Companies which are located in Germany because the German law ends at the German border.
JMich: So if I own a company registered in Germany which sells internationally, I do have to abide to the German laws, even if my buyers are not subject to it?

Yes, you have to abide the German law then. One of the main reasons why there aren't real big German digital resellers when it comes to Games. It is too complicated, too restrictive and too expensive.
