It's the best game store for the paying customer on Linux by a long shot
Store: that's a strawman argument; depends on what you prioritize.
Launcher: not by a long shot. And it's ugly too and themes are mostly broken now.
You can roll back to previous versions
Sometimes. For a while. Which doesn't help, if the major modder has given up, because of weekly forced breaking updates of the game. Can't just keep the version that works, even though games are one kind of software where updates are not critical.
My problem is more with their workshop mods. If you own the game elsewhere, you can only download them with their own proprietary and shitty cli tool and sometimes not even that. Yet most mods are there. I mean, just provide a API man.
I've played stray on both a pop!os desktop and a steamdeck and it ran wonderfully?
Doesnt even apply to other games either, just about every game ive attempted to run on steam has worked brilliantly, only issues being games with certain anticheats. Whereas other launchers like epic take 5 years to load and I couldn't get the games to even run. Gog doesnt have Linux support, however has worked somewhat well for me in the past once lutris got it working.
