are you sure it's not on german steam? check your steam settings if you have enabled something that blocks heavy NSFW games from appearing in your store, that might be what's blocking it
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.
I'd say Fear and Hunger is much more A/O than GTA or Witcher. Those games are built more around cathartic release; I wouldn't even call "Witcher" horror. The worse scene in Witcher 3 is the "Staked witch" scene, which is disgusting and pulls at the feelings; but it leaves players with greater resolve and empathy. In F&H, the harvestman was so much worse. Heck, even the consensual sex left a horrific pit in my stomach. The naked, dead strung up bodies, the "anal bleeding", limb loss, severed breasts & genitalia, cannibalism, self-harm, the helpless depression you just don't come back from...
Man, I love this game but I sure don't want my kids touching it before they're 18.
