Keep fighting the good fight.
And it really is the good fight in this case. I’ve been running Linux on my gaming PC for around four years with very little trouble. Games from Epic and GOG run very well(for me at least) through Heroic Games Launcher. I’ve been using Windows for work on/off the last couple of years, but especially since they “upgraded” to Windows 11, it’s such a relief to come home to Linux.
I started playing Stray on my Steam Deck a while back. It runs pretty much perfectly but I’ve got some problems with my left hand (I suffered a stroke last year) so I had to give up after a while. I too really loved the environment. The game is beautiful. I can’t wait for my hand to get better, so I can finish it.
I still have more games on Steam, however, Itch.io has had a couple of insane bundles in the last couple of years, which mean I have way more games and content on Itch than on Steam, which I did not see coming. I still use Steam the most, though, because I’m used to their interface and it works really well on Linux.
