They can be hard. I've tried Bloodborne, Elden Ring, and Sekiro. I got the furthest in Sekiro and kind of got the draw because, man, the high when you finished a boss. But the struggle, from my understanding, is part of the gameplay itself, part of the experience. It was too unforgiving for me. While I was happy finishing a boss, I didn't go into the next one excited for the challenge, I was dreading the upcoming hours of banging my head against the wall, so I just decided it wasn't for me. That part of the game play just wasn't appealing to me, doesn't mean it's bad of course.

I say give it a try! They always have Bloodborne on sale, nothing wrong with trying and deciding it's not for you, and it'll be awesome of it is!
