All games with pornographic content (of any kind) are also unlisted in Germany
>no that's not true
What part isn't? That all pornographic games are unlisted? Name one that isn't then. (No, Mass effect, Cyberpunk 2077 and Baldurs Gate 3 make Out with fade to black isn't pornographic. Name a single game where genitals visibly touch genitals)
>They'd need special age restriction (USK)
USK is literally something applicable to all games and necessary if you wanna sell them in physical stores here, goddamn undertale needed USK for physical versions. Why are indie games that aren't pornographic still available if that's the reason?
