I got the collection on Switch (both of them). X1-X3 I've played before many times, but the rest I realllly couldn't manage.
But someday, I'll return to them again.
You're right, though. Time is precious, and the rush I get from accomplishing something difficult in a game has somewhat diminished. I have quite a few Metroidvania-ish type games where I got stuck on the final boss and wound up setting it aside because what I *really* like out of those games is the exploration and atmosphere. And since I already did most of that, the motivation is rather lessened. (Hollow Knight being the biggest one here).
Maybe there's a heaven where I'll be able to dedicate 1000 years to speedrunning, collecting Shiny pokemon with max IVs, and beating I Wanna Be the Guy, but on earth I've got a lot of other stuff I want to do.
Makes me wish there were more atmospheric games that weren't about hard boss fights and tricky jumps. Something along the lines of a classic adventure game.

Last game I finished was probably Baldur's Gate 3?
