I'm going to make this point again because it went unnoticed due to the sheer amount of comments, but you wouldn't complain about a Rubik's cube or crossword puzzle being too hard or anything else designed to challenge you. I'd argue that without the difficulty of solving a Rubik's cube that toy would be lost to time. The only reason it still exists today is because it was so hard to solve for children when it was released. Souls games are the same. The only reason we still talk about them and the only reason they gained the popularity that they did is because of the difficulty.
I remember distinctly picking up dark souls on sale on a whim before it started really entering mainstream discussion. The guy working at Gamestop warned me that people kept returning it because it was too hard. I took it home and played it and really learned the mechanics then I brought it to my friends to try. They learned the mechanics and since then we've had an unofficial race to see who can beat the newest FromSoft game fastest. It was the difficulty of the game that made it so addicting. Without that the game would be boring and no one would know what it was in 2025. If you don't believe me install the easy mode mods and come back to let us know what your experience was like.
