I use Arch for all my computers, including my "critical" systems. I only do full upgrades when I know I have the time to troubleshoot something broken, but rarely need to do so.
More than this, I actually use Arch as the OS for thousands of computers for my work that end up in customer hands, who expect stability. I'm not sure at what point it stops being Arch, though - I pin the package repositories to internal mirrors with fixed package distributions from specific dates to control the software that goes to them, so it's not really rolling release anymore I guess - I control the releases and when updates go out.
Arch is what you make of it. My Arch project desktop pc is constantly shifting and breaking and needing attention as I continually improve it and play with things. My Arch laptop that runs my life and work and is the most important computer I own is a paragon of stability and perfect functioning.
I've been working through my first playthrough of Cyberpunk 2077 - it's fairly enjoyable, I'm glad I ignored it outright until well after big patches rolled out. There's something very satisfying about blowing up enemies through a camera.
I've also picked up Dwarf Fortress (Steam) for the first time. It has a lot of depth but has been fun to learn and try and figure out. I just flooded a section of my fortress by digging into an underground river.
My chill-out puzzle game has been Can of Wormholes and it's pretty fun! It's weird for sure... but definitely fun.
