Depends what sort of game, I've got better and better at things like Stellaris as I get closer to 40 and I usually have to play RPGs that are less reaction based on higher and higher difficulties to feel challenged.
In contrast I found myself struggling with Elden Ring when I used to have a comparatively easy time with Dark/Demon Souls and Bloodborne.
I don't think I'd have a hope in hell of playing fighting games or racing games like I used to in my teens.
Stellaris.
I'd end up staying longer than a year.
