Soulsborne games in general. I have found some exceptions (chief among them Jedi: Fallen Order), but for the most part, I just find the games too frustrating to be fun. I'm not saying they are unfair, but I can tell you in Dark Souls 1 where my exact "this game is not for me" moment was. It was a bit into the game, when fighting the twin gargoyles. I was having problems, even with summoning a spirit, so I went to a walkthrough to try to get some tips, see if I was missing something.
Walkthrough described it as one of the easier boss encounters. I decided that if that was easy, I wasn't going to stick around to see what was hard.
