At some point you recognize the game is just giving you another to-do list.

Nah, I think that starts happening when you first get a job. Jobs take longer than school and generally are more labor intensive, and there's also the commute, and when you get home you have to do chores and either make healthy food or eat something garbage for your body, and that's just as a single person or a couple. It's no wonder everyone's tired, the 9-5 grind can be really exhausting, and when you're tired anything that takes effort feels like a grind.

In the last couple of years I feel like that. Games that require a lot of time to get into, or to complete, feel like not accessible anymore.

I play either those games I used to for I already know them, or something with a very short route to dopamine. I've found playing Burnout series not causing me this burnout, kek. Just racing, no long-time investments, just crushing cars and see them fly. A good way to rest after a day of complicated tasks and decisions.

Idk about you but I'm a dev, and when you have a job tbag keeps your brain ON a lot of the time, I feel like it's more common to want to turn it off in your down time

Nah, life's exhausting and the older you get the more exhausting it becomes. Work requirements and responsibilities typically increase as you age, children are a black hole of time (as fun as they are), your body just starts to say "fuck this" and give up in creative ways and you just generally have less energy than you did the day before.

I feel like the older people get, the more they tend to prefer to watch others do things rather than do them themselves.

I relate hard. Multiple times before, I've spent hours and hours scouring the internet for a download link to a game, or even a tool or library needed to make it work. I'll open the folder at 99%, ready to install 0.05 seconds after it's downloaded. I'll launch the game just to make sure it runs okay on my system, then give it a little whirl, and even then, it's rare I'll ever see beyond the tutorial, if that.
