I've expressed this many many times to him over the years. I've said something like "I want to play games to have fun. If the game isn't fun for me, then I will not play it anymore".
I believe that he understands this. However, he just wanted so much to understand Elden Ring and beat it.
Personally, Elden Ring is NOT fun to play and that's why I don't play it.
I'm just astounded that my 8-10 year old son persevered so much to beat it.
Elden Ring and Dark Souls games are not fun to play per se, but it's very rewarding due to the difficulty and skill required. That sense of accomplishment is why a lot of people play, even if it's not explicitly fun to keep dying and restarting. Not everyone's cup of tea for sure but many good lessons and skills to be learned playing it
I'm in my 30s. I'm gradually getting calmer. But seriously, if a game doesn't induce the urge to throw objects around the room from time to time, it probably won't make my list of favourites.
