I'm not that old, but time is flying at me, and in my experience it's that older people don't have the same time options and skill level to "git gud" at newer games and that just makes online games less fun for some of us. So single player games we can take our time on and finish without somebody in the headset barking at us. I really prefer things like Fortnite STW these days, I can log in and choose to pair up with others or go it alone and I have the option to choose my difficulty level with the different biomes.
It's ok, one day Gen Beta will be the same way with the Z's, it's the circle of life.
I still play online some, but I've come to the conclusion I'm not great at it and never will be and I'm ok with that.
From your list AMD+Intel is the most believable, allegedly Qualcomm has already made inquiries about buying Intel.
