Oh, is it that time again? Time for warm tea, cozy blankets, and cowering from wolves in The Long Dark? This is the game that fully convinced me on the steam deck.
Never tried a trucker sim before, usually more into base building, but daym--throw some scifi in there and I'm hooked! All the levers and switches work and are satisfying to pull. Blast through the short tutorial, put on some music, decompress, and just driiiive(/float).
I'm not sure if it has Autumn/Fall vibes, but I'm tempted to get Slime Rancher 2. I guess it's appropriate for harvest season, as you're farming and harvesting slimes? Something about it (at least I got this impression from the first game) feels cosy and perfect to play while the days get colder.
Don't be put off by the comparisons to dark souls, the main reason I said it is relaxing is the very lenient way it deals with its survival mechanics. Especially if you have a decent sized group you could totally just farm and play viking stardew valley.
