Patient Gamers

Hyper Light Drifter would be my personal recommendation. My playthrough lengths ranged from like six hours on my first run to like, an hour and a half when I decided to try and beat it quickly? But the game is really gorgeous, and a lot of fun to play

The Stanley Parable.

Dishonored 1 and 2.

What remains of Edith Finch, a very emotional and wonderful game, short and bitter sweet.

I'd go so far to even gift it to people. Outer Wilds make you feel small and huge at the same time.

Opus: The Day We Found Earth, another great short one.

Digital - A Love Story and its not so close successor Hate Plus. These are digital novels. The former is a story set in a cozy 80s BBS network and the other in an archeological space ship retelling stories related to old Korea. Both touched me very much.

Ratchet and Clank (into the) nexus on ps3 is like a 5 hour game. It also nicely ties into the latest game if you've yet to play that

A bit old, but gold: Fate (the dungeon crawler one). It's a bit low-poly by today's standards, but it's so fun and has killer music, lots of spells and weapons, tons of interesting enemies and can be beaten in like 6 hours.

If you wanna have some nostalgia for 2000s era AOL chatrooms you ahould try Emily is Away Too

Most point and click adventures take about 6-10 hours in my experience. My favorites are the Monkey Island and Deponia games.

I think Cocoon will fit in 10 hours. It did for me.

Resident Evil 7 & 8. Seven sets a new protagonist in a series reboot sort of way, so you might miss some Easter eggs and callbacks but playing the previous games AT ALL. Its meant to be an entry point in the series.

Ori

If you're good enough, Vanquish.

Inscryption

I just played through the entirety of Storyteller in one sitting but had a riot of a time with a few friends. I think I spent about 2-3 hours finishing the campaign and will probably spend about another hour finishing the last of the achievements when I next take a crack at it.
