Learning about the concept of enshittification (https://www.wired.com/story/tiktok-platforms-cory-doctorow/) made me suspect that this might be going on with games too. I mean these always online and monetisation trends seem to suggest so.
Though for me it‘s also the age and work, quest logs remind me of ticket systems and grinding of more repetitive work and it all lost it‘s shine. I enjoy games still, but less often I would say.
