Steam is actively blocking it from the german shop.
They did the same thing with the first game.
Could be due to the themes of the game.
But it's true that some triple a games do the same things even worse-
Apparently, it works like this;
Games with Adult Only Tag are automatically hidden from german users, the tags are decided by the developer.
Pretttyyyy sure Fear & Hunger does not fit the Adult Only descriptor. Sex isn't in the forefront, and frankly there's worse sexual content in other games like GTA or Witcher.
I could of course also be wrong, but i'd love to have it on my steamlist. Heck, I'd even buy it again lol.
Would also make it easier to gift it to people.
