I use the Steam version with the -provider Portal launch modifier (lets me use my old ANet account)

Dropping by to throw some more praise onto the pile for Nobara Linux - it’s my current distro and I have an AMD RX 6700 as well. All the games in my Steam library work great, including Baldur’s Gate 3 (no tweaks necessary other than enabling the latest GE-Proton version). Unfortunately I haven’t played any of the games you listed; my preferences lean mostly towards RPGs like Elden Ring, Path of Exile, Guild Wars 2, Valheim (with mods!), Enderal and so on.

Surprised no one mentioned Enderal yet. It’s a total conversion mod for Skyrim (special edition) and it really fits the bill of mystery/horror. It’s my favorite game from a narrative point of view; the soundtrack and voice acting is also excellent, and I have re-listened it long after finishing the game. The only issue would be that you mentioned you would prefer a more linear experience, rather than an open world. The main quest is fairly linear, but you can still go off the rails and explore - but the pull of the story will always set you back on track.

One of my favorite tracks, which summarizes quite well the atmosphere of the game - https://www.youtube.com/watch?v=JKLkOnvFG5w

ProtonDB lists it as playable on SteamDeck; the game itself is free, although you will need Skyrim Special edition (which is around 10$ on Steam right now).

A note for folks who didn’t know this - if you’re using kbin, when you search for lemmy communities to subscribe to you should remove the ! from the search query (eg, use nostupidquestions@lemmy.ml instead of !nostupidquestions@lemmy.ml). This way you will find the community instead of related posts.
