I wouldn't say my love of games has diminished but it has changed. Certainly I've found my focus is firmly on older games and systems. I've gotten really into my older FPS games, Quake especially, to the point that I'm getting deeper into creating maps for it and I have enough content there to keep me going for years.
It's not that I don't like newer games. The indie scene has some wonderful stuff and I'm still there for the biggest titles, but I'm less tolerant of bullshit and timewasting. Stuff that leans heavily into Gen Z and their taste I do find a bit alienating as well. I'm happy to say I've never touched Fortnite and never intend to. It just looks like everything I hate in modern games. Same with Forza Horizon and it's utterly awful "influencer" aesthetic. More than ever it's not the gameplay that sucks, it's the presentation.
EDIT: That's not to say those games are bad. They're just not for me. And that's fine, not everything has to be. I'm in my 40s now. I'm no longer the primary target market for these companies.
I think it's that I've become more picky over time. While I do broadly try to keep up to date with what's popular and doing well I no longer feel the need to play everything.
My interaction with games is definitely broad but shallow. I'll try loads of things on a whim but I rarely stick with anything for long. Once I think I've had my fill of something I'll happily move on.
It doesn't help though that modern AAA games are just one big homogenous blob of the same gooseberry fool with a different texture set slapped over it.
