I want to try and play some more games. That feels more fulfilling if you play games that you can finish and be done with.
So what are some good games that have zero (or close to zero perhaps) replayability? I'll start with my own suggestions:
Return of the Obra Dinn: Amazing mystery/detective game. However once you've played it, you basically can't play it again as you remember the solution already and the challenge of the game is trivialized.
Chants of Sennaar: Really great game about deciphering languages. However, once again, by playing the game once, you'll remember the languages and the game has no challenge any more.
Outer Wilds: Mystery adventure game. There is some replayability as there are perhaps areas that you can still explore, but largely once you figure out the mystery and complete the game, there's not much more to experience. Some people speedrun the game though.
All of the above games I value extremely highly even though I only played them ~8-10 hours.
Thomas was alone.(I recommend this one up there with obra dinn)
Spec ops the line
Dlc quest
Limbo
For something quite a bit different, amnesia the dark decent.
This one might be controversial, but the original BioShock, I played it how I wanted, and >! Got the good ending!< And never felt the desire to pick it up. If you're a completionist on the first run, and it isn't very difficult to do (very rewarding I'd say), then there's 0 reason to pick it up again. I felt the same about replaying BioShock infinite, but more because I just didn't want to play it again (I felt like it had much more story to offer, and sidequests to do, but I didn't get any of the same satisfactions from the game, first one was done and wrapped up nicely, third one was barely unraveled and I chose to read other people's ideas of how it had ended)
Spec Ops The Line has sadly been delisted and is no longer available for purchase. If you already got it, you're fine, but the only way to get a copy now is 🏴☠️🏴☠️🏴☠️
I played amnesia exactly once and still haven't brought myself to replay it. I tried a year ago (originally played in 2012) and, while I admit I didn't give it much effort to relearn the mazes, I didn't feel too motivated still remembering most of the plot and of course the finale.
