Hollow Knight, Bioshock, Dark Souls, Resident Evil 7/8, Shadow of the Colossus, Soma, Sifu, Tunic, Outer Wilds and Firewatch.

Monkey island, Myst, Riven and Heavy rain.

I agree with so many here, but I have a new one.

Dredge.

It just seemed like a fishing simulator, but it got creepier as it went on. Definitely an ending I didn't expect. That may have been me just getting too into finding every fish.

Great gameplay loop and played on steam deck excellently.

I like your pick, Morrowind. I was very hyped to play it, and when I could finally own it, it was even better then I had hoped.

I think my pick would be Inscryption. What a weird and delightful game :)

I want to say Fallout 2 but then again 46 year old me would probably give up halfway through the fucking temple of trials.

That shit was brutal if you tried to make a non combat based character.
