stryx: If your company is located within the EU and you are (also) selling to German customers, you'll also have to abide by German law, because the German law is enforcable through EU law.
Show me that specific law pls and show me a few shops outside of Germany which really follow the German youth protection law (I can only name 1 which is Ubisoft).
DanTheKraut: Companies which are located in Germany because the German law ends at the German border. The BPjM can't do anything when it comes to none German stores (located in Germany) except indexing the website and there are no shops on the index.
toxicTom: gameware.at and some other store nearly got "indexed" - which essentially means that google.de can't list them. It took them a lot of effort to prevent this...
A company like GOG indexed basically means killing it for the German market.
As mentioned before there are no shops on the index only 2 Aamazon.co.uk sites from Dead Island.
