I'm requesting for recommendations for games that stand out from the rest in their genre, and not in the sense of being the best game in that niche but actually bringing something new and innovative to the table. I've not had much experience in gaming, but I have a few games to give you a hint on what I am talking about:
Superhot: Time only moves when you do
Viewfinder: Convert 2D pictures seamlessly into interactive 3D environments
Superliminal: Change size of objects by working with perception
Portal: Portals
Scribblenauts: Summon objects by describing them in a notepad
I am not focused on the story, no. of hours of playtime, date of release or its popularity. It just needs to be playable and be enjoyable (and be available in PC).
I have a couple kinda unique things to suggest. There is a small indie game called Eversion that you can find on Steam. The core mechanic is about shifting to these different planes of existence to finish levels. You can only shift at certain places and shifting opens up pathways that weren't there before. Its retro style graphics and otherwise very simple controls.
The Turing Test is a puzzle game like Portal, but instead of portals, you have a gun that can be used to move energy orbs from around the rooms to unlock doors. The game feels like it encourages creative problem solving a lot more than most puzzle games.
Catherine. Catherine is a game in a few styles. You spend part of the time at a diner/bar interacting with people. Then you go to sleep and in the dream world you ascend towers using moveable blocks that you must climb. Sometimes you are chased up the tower by a boss enemy. There is no combat in the game. It's about ascending the tower as fast as possible at night and progressing the story by day.

Along those lines I'd want to recommend the Talos Principle as well.
And also the Witness, which does fantastic things with environmental puzzles.
