I don't think u can add a porn game on steam
yes there are lewd games on steam. but blocked for german users. german laws require steam to implement a reliable age verification. instead of bothering with that valve decided to block naughty games for german users.
i think in china its a similar issue.
so for users from those regions itch is the better choice.
(itch just doesnt give 2 sh1ts bout that in general)
Damn, didn't know German have region lock for lewd games, always thought German was more sensitive with "Violence and WW2 history". Since I remember Germany used to make alot of Lewd games, like Lula Virtual Babe in the 90's. I think China are allowed to buy lewd games, but not allowed to make lewd games with full frontal nudity and segs. This is why alot of Chinese games tend to be on Scandily clad females but no actual lewd situation. Although alot of lewd games have Simple Chinese, so I assume they have lewd games.
the games arent actually forbidden. nobody is forcing valve to block them for german users. that's their own decision because they dont wanna bother with reliable age verification.
the funny part is: if u get keys for lewd games like from indiegala or elsewhere, u can still redeem them on steam as german user and play em.just the shop and community pages are locked for german users.
