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.
Superliminal was cool, but I just didn't enjoy it. It was fun for a bit, but I feel like the mechanic overstayed it's welcome for how simple it is. There's not very many unique ways to use it. That's probably why Valve abandoned the idea too.
Still, it's interesting and worth a shot. Plenty of people love it.
I feel portal could be replayed if you focused too hard on the puzzles the first time through, there were quite a few secrets worth exploring in that world, though none too deep unfortunately
I feel like portal 2 can get by on a playthrough every so many years based on the writing/VA making it enjoyable even if you half remember the puzzles.
Awesome game. I was high on cannabis when I played it, and managed to beat it in one sitting about 10 years ago. I want to play it while high on shrooms, that would be even crazier.
I was going to write anti chamber, because I never want to play it again, but %'s 30-90 of the way through the game I was itching to start over. It had me so hooked, but then the ending just took the wind out of the sails so hard. Heck maybe 10-98% of the game had me itching to replay it.
