Censored version is already done though. Took less than a week.
The main problem with the VPN stuff is that Germans have no idea that Steam is banning 18+ releases for them, so they won't think to use a VPN.
Steam sadly can't be tricked by a vpn alone (I'm german, I tried), because they base your location on your payment method as well (don't ask me how, I don't know). So you would have to jump through even more hoops. A censored version with decensor patch is the most comfortable for german users afaik. And I can receive these games as a "gift" from someone.
