Same with me. When I was younger I was able to just enjoy myself without mixing irl thoughts. Unfortunately these days as an adult if I'm stuck in a game or have to chip at it in some tedious fashion, a part of my brain goes "you can spend this time learning something new or productive irl".
I think my attitude changed the games I play also. I used to play MMO when I was younger but FPS games give me that dopamine rush without any commitments.
Sadly it's only when I'm sick do I feel I'm able to just cozy up without these "you can be doing something else" thoughts and truly enjoy games for what they are, tedious or not.
After beating prepatch PCR, I switched back to Call of Duty for a bit.
