If you mean enjoyment decreasing, yes, it's pretty bad.
I can still enjoy a game but it's much harder to get into. The whole spell that tricks your brain into enjoying games, breaks easier now. If I'm in any way not locked in mentally, I feel like my time is being wasted. Pointlessly open world games are a big offender here.
I did eventually finish Elden Ring, but I enjoyed Sekiro so much more it's not even close.

It really doesn't help that most new games are actually shite, the industry needs a kick up the arse. I spend almost more time looking for games than playing them these days.

If you meant skills worsening with age, no, I don't have that problem at all.
