dont really think I need to say it, but both feature content that is not for everyone, but I guess that should be clear already, seeing the thread title.
Now there might be a few more translated ones out there, which I cant remember right now, but as you might have noticed already, what you are looking for is kinda rare in the western industry. If you are up for playing untranslated japanese games or can use a machine translator, then there would be quite a lot more available. Some might not even be too bad untranslated, for example platformer games.
Edit: Just remembered another one that could fit, name is Cursed Armor
