Returnal, Resident Evil REmakes, most Giant Bomb games, Firewatch, Hellblade…

If you liked Alan Wake, definitely give the RE remakes and Hellblade a shot, and don’t sleep on Firewatch. In fact, Hellblade: Senua’s Sacrifice is probably one of the most thoughtful and atmospheric experiences in gaming (at least in the field of 3rd person, pseudo action games).

I went on my steam profile (note these are all PC games, but some are on console) and looked at all the games I finished in under 20 hours at least once and enjoyed so I’ll just list them here. It’s in descending order from most (20.1 hours) to least (68 minutes):

I put a star next to the ones I’d recommend in a heartbeat even without the 20 hour limit.

• Mirror’s Edge ★
• The Stanley Parable ★ (although may take you at least 20 to find all endings / easter eggs / secrets)
• Deus Ex: Mankind Divided ★ (due to the fact that it’s the middle game in an incomplete trilogy, also recommend Deus Ex: Human Revolution but that’s more than 20)
• Hotline Miami ★
• Little Inferno
• Tom Clancy’s Splinter Cell
• Dishonored ★
• Myst
• DOOM (2016) ★
• Wolfenstein: The New Order ★
• Portals 1 & 2 ★
• Return of the Obra Dinn ★ (beat twice in 9 hours)
• Kentucky Route Zero ★
• The Henry Stickmin Collection ★
• FAR: Lone Sails
• Titanfall 2
• DUSK ★
• COD: Modern Warfare 2
• Ghostrunner (didn’t like this but it seemed most people who weren’t me did so i’m putting it here)
• Thomas Was Alone
• Jazzpunk: Director’s Cut ★
• Gunpoint ★
• Orwell
• Firewatch
• Superliminal ★
• Observer_ ★
• SUPERHOT ★
• The Beginner’s Guide
• BattleBlock Theater
• INSIDE ★
• EDGE
• Quadrilateral Cowboy
• Journey ★

edit: saw u said “story heavy” so i removed some of the arcadey ones. Some of these aren’t exactly “story heavy” depending on ur definition but they at least have a story

I’mma do it, I’mma be the one to bring up Undertale this time (estimated 2 hours, worth a few replays), there’s also little nightmares (2-4 hours depending on platforming skills) which is a spooky little game, but not too spooky if you ever play in front of the kids.

Portal and Portal 2 must be on this list. If you’ve never played then, you must. It is that simple.

I’ll always recommend What Remains of Edith Finch into these sorts of conversations. Absolute one of my favourite shorter experiences.

Bastion or Transistor, both early Supergiant games.

Depending on your puzzle solving abilities, Outer Wilds (not Outer Worlds!) should only take around 15-20 hours.

Extra bonus, it can be played in very short sessions very easily and has a great in-game log of events in case you have to put it down for a little while.

Have you tried What Remains of Edith Finch? It’s a good story heavy game that’s pretty short. Return of the Obra Dinn is a deduction puzzle game that can be done in short sessions. Celeste is also good for short sessions if platformers are more of your thing.

Journey is a game you could easily finish in one sitting. Short but sweet, and very easy to get swept up in the atmosphere.

I haven’t finished Spec Ops: The Line, but I recommend that. It looks like your average American propaganda third person shooter but the story is actually super interesting and thought provoking. Looking at https://howlongtobeat.com/, it’s 6 hours for the main story.

I’m usually way more into short arcadey yet narrative games like Hotline Miami, but based on your list I’d wholeheartedly recommend What Remains of Edith Finch. It’s a bunch of very short story vignettes, so even if you only have 30 minutes you know you’ll complete one.

Night in the Woods might also interest you. I would always play one in-game day (which is about 1 hour each) to relax before going to bed.

You should give Guardians of the Galaxy a try. I’m not really a Marvel fan but the game is great and should take around 20 hours to complete.

Jade Empire - a little older Bioware action RPG, originally for the Xbox, but can be found on GOG. Runs between 12 to 20 hours.

Undertale - my favourite game of all time, easy to play, excellent story, and incredible soundtrack.

Gris. It’s like playing an art piece.

I’d look at Telltale-style games. They’re roughly 10 hours each ( five 2-hour ish episodes) and are almost entirely story driven. The gameplay is usually very simple. You choose dialogue choices to drive the story.

The best Telltale games are in my opinion: The Wolf Among Us, Tales from the Borderlands, The Walking Dead, Batman: The Telltale Series and its sequel, Batman: The Enemy Within. They’re also releasing the first episode of The Expanse (based on the TV show since the character Camina Drummer does not exist in the books) later this month.

Another series that is very much that same style but by different devs is the Life is Strange series. I’ve played the first one and the prequel called Before the Storm. They are very emotionally heavy stories so I’m taking some time before I can go into the sequels but I absolutely love that series and will preach it to anyone who will listen.

10 hours is definitely short but it also helps that they are all done in 2-hour episodes so you can easily take breaks.
