I've actually lost interest in more modern games, I think it's mostly the focus on graphics, animations, and strong narratives. If I do play something these days, I find myself picking up older games that actually are quite restricting based on the technology they're built for.

I've had more fun playing Resident Evil 3 (PS1) than I have anything more modern. There's something about the gameplay that feels more immersive and rewarding. Perhaps it's a result of the camera angles and weird janky tank controls. The way it feels slower to perform movements and actions I think makes it more immersive as opposed to analogue sticks being pushed around.

One thing I do know I'm not a big fan of these days is the games-as-a-service notion. I have zero interest in live services when they're designed to keep you in and paying. I even have noticed some ignorance towards really cinematic games with very linear level design and heavy animations towards performing actions.

As @holoz0r said: writing hasn't kept up. Stories these days are a bit too centred around realism and giving players something to relate to, rather than going wild with fictional worlds and characters.
