Screen is not the best, but everything else is superior. SteamOS is much better than Windows, IMO. Though I don’t play multiplayer games and I’ve read some anticheats don’t run on Linux. The only multiplayer game I play from time to time is Fall Guys and it works. Emulators are actually where Linux shines and especially Steam Deck - there’s an app called EmuDeck that sets up all the emulators you could think of and makes it work really easily. For Epic and GOG games I use Heroic Games Launcher and it works well, I played Spider-Man and Fall Guys from Epic and most of my library is on GOG.
Basically Telltale games. I include first Life is Strange in that because they managed to out-Telltale the Telltale. I love my games basically as an interactive story.
Edit: Also Heroes of Might & Magic. I want more good ones, 6 & 7 sucked tremendously.
For me it’s about the story, I basically only play games that have an interesting story (and some Vampire Survivors here and there). So I don’t care for challenge or progress.
