Do you just mean no sexual content or nudity, or is that a blanket ban on any kind of graphic violence?

By NSFW I primary mean pornographic content. There are many dungeon crawlers with partial nudity and I will allow that, but don't go hardcore hentai or porn. Violence and gore is allowed, within reason. Check out this classic https://dungeoncrawlers.org/game/bloodfest/

Okay thanks for the clarification. I was thinking of going for a horror vibe with my game.
