Portal?

Outer wilds. It can be longer for some but finishing it in a single sitting or two it hits best. A deep emotional experience that you can only ever truly experience truly the first time. So avoid spoilers at all costs.

Also Firewatch

A Short Hike is a great little platformer you can finish in a couple hours.

Super Mario RPG is a classic and can be squeezed into 10 hours if you rush, but probably closer to 1215.

Mirror's Edge - a perfect way to spend 5 hours

Journey is a game that has stuck with me for the past ten years. It took me an hour and a half to complete.

Ordered-ish by recommendation:

• SUPERHOT (it's the most innovative shooter I've played in years)
• Hellblade: Senua's Sacrifice
• Sayonara Wild Hearts
• Carrion
• Planet of Lana
• Jusant
• The Artful Escape
• The Gunk

I always check https://howlongtobeat.com/ before starting a new game

I also tend to prefer games that are short.

Here are a couple of my PC recommandations, in no specific order :

Somerville

Jusant

Planet of Lana

Limbo + Inside

Little Nightmares 1 + 2

Cocoon

Solar Ash

Tunic

Cult If The Lamb

Have A Nice Death

Death's Door

Stray

Trek To Yomi

The Stanley Parable

I also love short-ish games, so hopefully one of these strikes your fancy. You didn't specify a preferred genre or other games you liked, so I'm going to just throw some out there:

Adventure/Puzzle

• Stacking - fun adventure puzzle game based on matryoshka dolls
• Little Nightmares - fantastic puzzle game stuff great atmosphere and horror elements; similar to INSIDE and Limbo
• Abzû - underwater exploration with light puzzle mechanics
• Ys 1 and 2 - pretty old, but it's my favorite Ys game; Ys Origin is a bit newer, but also a bit longer (~11 hours per playthrough, need 3 for full story, but each plays differently)

Puzzle

• Manifold Garden - puzzle game where you manipulate gravity
• Hexlogic - sudoku-like
• SUPERHOT - shooter that plays like a puzzle game
• Magrunner - just ignore the story, the puzzles are pretty good
• Portal - the OG puzzle game, must play if you haven't; second is about twice as long

ARPG/Souls-like

• Death's Door - just started, but it's looking good
• Ittle Dew - Zelda-like with lots of satire about the genre
• Furi - boss rush only
• Titan Souls - boss rush, but both you and the boss has 1HP

Narrative heavy

• Telltale Batman or The Walking Dead - narrative heavy game with walking simulator sections; choices matter (but not a ton); great if you want a decent interactive story
• What Remains of Edith Finch - explore your old home to learn everyone's secrets
• Oxenfree - explore Island to uncover its secrets; replay value for alternate endings

Metroidvania

• Headlander - Metroidvania where you play as a disembodied head that can attach to other bodies
• Ori and the Blind Forest

Point and Click

• Darkside Detective - point and click with a great sense of humor
• Broken Age - you're a virgin about to be sacrificed, and you're not sold on the idea
• Deponia - earth is completely wrecked, and you want off; quite funny

AAA/high production value

• Ryse: Son of Rome - not amazing, but a pretty satisfyingly average experience
• Call of Juarez: Gunslinger - shooter a bit after the US civil war

I have more, just let me know what you like and I can try to give more recs.

Well-reviewed games you can 100% in less than 10hrs:

• Portal
• The Henry Stickmin Collection

• Pineapple on Pizza
• There Is No Game: Wrong Dimension
• Doki Doki Literature Club
• TOEM
• Finding Paradise
• The Murder of Sonic the Hedgehog

Well-reviewed games you can probably beat in around 10hrs, but not quite 100%:

• Portal 2
• Vampire Survivors
• Pizza Tower
• Katana ZERO
• A Hat in Time
• Resident Evil 2
• Hotline Miami
• The Wolf Among Us
• Undertale
• Papers, Please

Edit 2: I missed the part about low-end hardware, but it sounds like the only ones of these you may not be able to run are Stray and Resident Evil 2

Antichamber - old revolutionary puzzle game, confusing at times
Baba is you - a great puzzle game
Outer wilds - experience that is one in a lifetime, go in blind
Return of obra dinn - you are a detective

In no particular order:

Metal Gear Rising Revengence

Psychonauts 1

Bladed Fury

Ori and the Blind Forest

Unpacking

Portal/Portal 2

Bastion/Transistor

Any member of the Shadowrun RPG trilogy

Little Inferno

Planetarian

Games of about 10hs from before 2019?

• King of Dragon Pass: Tribe management game/text adventure with illustrations. Felt it was interesting in both mechanics and vibes
• Plants vs Zombies: Addictive comedy-themed tower defense
• Alundra: PS1's Zelda
• Gris: Atmospheric 2D puzzle platformer
• Celeste: Rewarding 2D platformer with nice music
• The Lion's Song: Graphic aventure light on gameplay and heavy on story and atmosphere. 4 chapters about early 20th century Austrian artists and scientists with themes like art, gender, identity, memory, society, etc.
• Orwell: Keeping an Eye on You: You play as a government employee tasked with finding people deemed as terrorists by the gov by scouring their social networks. There's different ways to play it
• Papers, Please: Similar to above but as a border control agent
• The Banner Saga: Tactical RPG bases on viking mythology
• Rebuild: Gangs of Deadville: Management of a group/colony of customizable survivors in a zombie apocalypse. Web game

These are more recent but they should require very low specs:

• Roadwarden: Very well written and immersive text adventure with RPG elements. Low fantasy world, you're assigned as a roadwarden by a far away nation to a dangerous and sparsely populated wildland.
• Landnama: Viking tribes settling Iceland. Plays like a well designed board game in video game form. Real time with pause.
• Citizen Sleeper: Incredible cyberpunk text-heavy adventure with RPG elements and a narrative focused on being humane in a not so humane world with a not quite humane body

If it hasn't been mentioned, I think it's newer than 5 years but Return of the Obra Dinn and Curse of the Golden Idol are great short games that you can pick up and put down as you like.

Titanfall 2 is fun! I did the singleplayer in about 6 to 7 hours.

Portal 2

You absolutely must play Doki Doki Literature Club if you have not. It's free. Do not look up spoilers or be put off by the type of game or the setting. Just play it.

P.S. - "Doki Doki" the way you write the sound of a heart beating in Japanese akin to "lub dub" in English.

Return of the Obra Dinn. The 2nd game from the maker of Papers, Please. You're trying to solve the murders or disappearances of 60 people on a ship, using a watch that can view their moment of death. Insanely unique game, and it's hard to replicate that feeling of all the pieces of the puzzle falling into place that this game fosters.

Stray

I have seen it recommended somewhere in the comments but I want to shed some more light on this game: What Remains of Edith Finch. It is a walking simulator that should take about 2 hours and is best played in a single session.

As Edith Finch, you go back to the house where you grew up in your younger years to explore it. The Finch family has an almost genetic trait of bad luck; many of them have died before their time. You explore the house room by room and explore that person's last moments.

There is no gore or horror of any kind, but there are children that die, so if that is a trigger I would sit this one out. If not, it is currently on sale for less than €5. It is worth it.

Celeste. Not much to say except that it's a fantastic little platformer.

I think Bastion is a perfect fit for this

Chrono Trigger apparently. It feels longer, but if you are familiar with square rpgs… or Pokemon. You can get through it quickly.

I take my time personally, and like doing the side activities, and listening to the music.

Stray

• Firewatch (highly recommend!)

• Frog Fractions (game is best played blind)

Incremental Games: (best played blind)

• Eliza: A visual novel by Zachtronics, took me 10 hours to beat

• Tiny Bang story: wimmelpicture point & click. 7 hours.
• Call of Cthulhu: Horror walking simulator. 7 hours.
• Bastion: Amazing isometric action game by Supergiant Games. Rook me good 6 hours to finish.

• Homefront: USA gets invaded by Korea first person shooter. Good 4 hours.

• LIMBO: Same as INSIDE, same developer, great game, different story. 4 hours.

I don't think anyone else has mentioned Gunpoint! So.. Gunpoint.

Of these, the standouts that I've played so far are "Scanner Sombre" and "Unfinished Swan" for truly unique gameplay. "SOMA" and "Heavy Rain" for best storytelling. "Painscreek Killings" for best mystery (minus one very out of place sequence). "Forgotten City" for the best standalone Skyrim mod turned into a self contained adventure.

It's been awhile since I finished if, but if I recall correctly,Abzu was about 5 hours.

Limbo. Good game and it lasts only 2 hours.

Celeste!

(Unless you want to complete additional levels, which are still canon, then much much more).

I enjoyed Stray. It’s pretty short, only got stuck one 1 of the puzzles.

• Citizen Sleeper, it's so good you will likely not put it down until your story ends!
• Thomas Was Alone, amazing narrative platformer and all time favourite.
• Telltale Games, most of not all can be completed in 10 hours and they are all great. TWAU is the best one.
• Titanfall 2, one of the greatest campaigns.

You can finish a lot in 10 hours.

Lil' Gator Game can be 100%'d in like 4 hours or less.

The game is basically BOTW but smol.

Hellblade Senua’s Sacrifice

Bulletstorm, its stupid, its raunchy, and its hilarious, and it clocks in at about 8 hours.

Just throwing out my own recommendation for others, I really enjoyed playing Dredge over the summer, which ran perfectly fine on my 1070. Total playtime was about 11 hours and I don't feel like I missed anything or that it overstayed it's welcome

Dredge

Had no idea what to expect going into it. Had only heard that it was a cosmic horror fishing game and decided to give it a try. Ended up loving it!

Not a huge game in terms of scope but feels it nailed every mechanic and the art style and delivery is top notch

Journey

Inside

Adrift

Subnautica

Humanity

Telltale Games Wolf Among Us.

Bioshock comes to mind. You'll miss some side stuff with a 10hr play through but I think it's doable. Amazing game

I'm playing through the original metal gear solid and it has a pretty good pacing that keeps things fresh while also being a short game. I think you can beat it in about 10-12 hours depending on how much you call in your codec to get extra dialog if you want.

Metal Gear Rising Revengeance

It has zero filler, it's wall to wall balls to the wall nonstop action

you might exceed the ten hours slightly if you're bad like me and get stuck in the final boss for two hours but otherwise it's perfect

Helltaker is a little puzzle game that is free and short and sweet

The Curse of the Golden Idol was released in 2022, but could probably run on my microwave. It's a brilliant little detective game inspired by The Return of the Obra Dinn. Highly recommended.

Another detective game from 2022 I loved that's similarly untaxing on hardware was Strange Horticulture. You run a horticulture shop in a Victorian-y fantasy land where strange things are happening...

Both under 8 hours to complete.

May I introduce you to the Sega Saturn library. A lot of it is arcade style games, many of which can be beaten in 2 hours or less, but replayed nearly endlessly

Finished Cult of the Lamb in 6 hours when it released, and I wasn't slacking around. It's a town-building with some roguelike elements, the graphics are cute and nice, while it explores the idea of cult creation, doctrines, sacrifices and all the dark stuff.

• Max Payne
• SW: Republic Commando

VVVVVV

I really enjoyed Her Story, if you're into mysteries.

Not sure what 'low end' is for you but if you like puzzle games, The Talos Principle (2014) is fairly low end (plays great on my 6 year old PC) and can be completed in about 6-8 hours. Though, because it's a puzzle game, it could take much longer than that. Right now it Is $4.49US ($9.98US for the gold edition) on Steam. Puzzle logic is similar to Portal.

IIRC, Undertale was a pretty short game, and has as deep a story as games three or four times its length.

COCOON and Viewfinder are a couple of not-terribly-long puzzle games with super cool mechanics.

Brothers

If you’re looking for a little bit different and unique experience, you can try Katamari Damacy and it’s sequel, We Love Katamari

Instead of shooting enemies or run into the end of the stage, these games main gameplay is to roll a extremely adhesive ball (using both of the controller analog stick) to collect various random objects and junk and make it grow bigger in size. Each of the levels has a different objectives and size requirements that need to be completed for advancing to the next level. The game main campaign also has a very light storytelling too, typically involves around the protagonist and his abusive father who always command him to roll stuff up. The graphics are really minimalist and colorful, plus the soundtrack are the absolute fire, covering the multiple genres such as J-Pop, Scatting Jazz, Hip Hop Disco, and even Bossa Nova

Both games main campaign can be completed in less than 10 hours and runs great even on the low end hardware
