Maybe shooters aren't? I'm not into it and i still find the "just one more hour" games pretty much as regularily as ever (except the 2017-2019 which were really fucking dark age if you weren't into button mashing or platform jumping)

I think games are coming out that are still just as fun. The only reason I may have less fun with gaming is because outside stress in the world makes it harder to engage as fully with the games today
