synfresh: Right but traveling to the USA and buying something there and then going back is the same thing as using VPN, you are just physically doing it. I always understood region restriction based on country of origin, not what your citizenship is. If you live in a country you are supposed to follow their rules (in this example Germany). I still don't think that's DRM.
You do understand that it is completely legal for Germans to buy most banned games in the USA, don't you? Using a VPN to circumvent them detecting where you are when purchasing seems like a very different legal matter to me.
synfresh: Think of it like customs. There are certain things that are banned from entering the country. If you go abroad and buy something that is banned and then travel back, customs will not allow you to bring it in.
But they aren't, that's the point. We are allowed to own and import almost all games, the exceptions are largely the same as in any other western society.
Anyway, it may or may not be considered DRM, but it is unacceptable and once I've bought a game intolerable.
