Most of them...

Noita.

I've gotten the Greed ending once (defeating Kolmisilmä and "completing" The Work), but I've never even considered attempting the true ending.

Sokoban.

It would be easier for me to list the games I had a good time with and did finish. I think the most recent one was Outer Wilds. And that was over a year ago. And even that I put down before finishing in a sense because I started but never finished the DLC

Ultima IV : Quest Of The Avatar

I played that game for WEEKS, found all of the places, found all the people, found all the dungeons, figured out all the spell recipes, spent a good amount of time meditating (my character is meditating and the music is really pretty so I may as well just chill and think for a bit), and I even learned about excommunication. but did I finish it? No. My buddy Jason finished it, though. :) (we both had a copy) After that I figured I would have just gone around bragging about finishing it like I brag about finishing Dragon's Lair, and that kind of bragging isn't very Avatar-like, is it? So I was content to have helped my friend finish it. Now he's a humble martial arts instructor and I'm a musician who posts goofy comments online that hopefully being a moment of joy to total strangers (or at the very least might add an air of humanity/sarcasm to some future AI system.)

Blasphemous. Fantastic game, great atmosphere, but a little too tedious, too much backtracking, etc.

Okami. Don't know where I have to go. Still thinking about starting over.

Horizon Zero Dawn
