Would you count NG+ as replayability? I know for Nier Automata and Armored Core 6, it's basically part of the story and you haven't finished until you've unlocked all of the main paths. There is enough new stuff each playthrough for it to be unique though.

I would say Stillness of the Wind definitely falls into this category. A beautiful game about life and loss.

Breathedge - SciFi game where you are stranded in a small shuttle after your main ship exploded, you'll need to fly around in a space suit with limited air supply, gather stuff, examine objects to identify possible devices you can cobble together from random space trash, and eventually build and upgrade your equipment to the point that you can progress to another area, and so on.

Once you know how specific items are built, the solution is near identical, just some components might be drifting in another part of the screen.

the desolate hope. its a very unique robot themed game, but you only really need to play it once.

I personally think the main series Danganronpa games alongside Despair Girls have enough of a play through the main story mode (don't know if there are any other modes for Despair Girls) and then you don't replay almost ever type of gameplay since they're visual novels, technically. (I don't consider them visual novels because I consider those to be just images/animations and a text box on screen with no control over a character).

The 3rd game even has a mode you unlock at the end that has replayability, though, so I don't know if that would disqualify it.

Also, another game I like with pretty much no replayability besides watching your favorite scenes play out would be the point and click adventure game Beyond the Edge of Owlsgarde. It's a game that, if you know what you're doing, can be completed in 2 hours. My first playthrough took a lot longer though, since I didn't know what I was doing. Also, it only has 2 endings and if you miss the good ending, you'll get a hint at the end of the bad ending which will guide you to the good ending.

If you liked chants of shenaar, check out heaven's vault. I think it does what chants of shenaar does, but better, and it did it years before. It was a bit strange to me to see chants of shenaar get so much hype, but have heaven's vault stay slept on.

This game, One Chance, even goes beyond to try and make sure you only play it once

Darkspore.

as much I love the genre, but most single player 3D action/adventure platformer games that are based around a story OR fully arcade-y.

both aspect looses their point if you 100% the game.

Like, I just finished New Super Lucky's Tale, and though it was an excellent 3d platformer, I don't think I'll start a new game.

but not only 3D games. Like Shovel Knight also falls into this category. Amazing and exciting game, but other than a harder difficulty (as New Game+), it doesn't really have too much of a replayability.
