DiePesto: Thanks to the gog version, which is easily patched to be uncensored, I can play the game without vpn even though I am not supposed to due to German law.
Should note, the german law doesn't have a problem with lewd games - quite the opposite, if anything.
The issue is that Valve is refusing to implement a different type of age check. They're now mandating that your age verification at least makes a cursory effort to verify the actual age, instead of just being a "Do you want to see this page or not"-popup. Ready-made solutions exist, they're not difficult to use either after all plenty other pages such as Amazon have been using them for years due to similar limitations on e.g. mail-ordering chemicals or booze.
Just that this part of the law now also applies to age checks on AO games, and Valve is refusing - at least so far - to do something about it.

I mean I worked on a website before that allowed people to order cigarettes, and of course we had to have such an age check, too. Like I said, ready-made solution we got from another company, and it was cheap as dirt, too. Probably more corporate laziness than anything else.
