World of Warcraft

The one that I thought of immediately is Valiant Hearts: The Great War. It's under 10 hours if I remember correctly and it's at 3,74$ on Steam right now.

Another one is Pentiment which is at 10$ until December 4th

not exactly must plays in the general sense, just my suggestions

Real answers:

Half life 1+2 and episodes (2 is the best one though and the best fps ever made)
Any Zelda game excluding BOTW and TOTK
Bioshock series (escpially the first one though)
Deadspace
Left 4 dead 2
Crysis
Resident evil 4
Cod 3 to modern warfare 2 (campaigns are fun and can be done in a 4 or 5 hours sitting, not really a must play though)
All gears of war games (2 is the best)
Halo 1-3 campaigns
Goldeneye
Oregon trail
Original tomb raider (1996)
All 2d mario games
All of the Kirby games
Age of mythology
Warcraft 3 campaign
Mario rpg and paper mario
Donkey Kong Country games
Limbo
Tale of 2 brothers
Luigi’s mansion
Batman Arkham asylum
Uncharted 2

I would do almost anything to experience these for the first time again

i dont know how long disco elysium takes but if you want something single player its a must play imo

Real

Not a big gamer these days but one that has stuck with me was What Remains of Edith Finch & it’s extremely short.

Max Payne 1/2
Jsrf/bomb rush cyberfunk
Shenmue 1/2
Hotline Miami 1/2

Idk about less than 15 hours tho on some of these, I got some crazy playtime on a few of em I'm throwing twilight princess up there for posterity but it's for sure above 15

Shenmue 1 and 2 are like playable old school anime, loved every second

Uncharted series
Max Payne series

Mafia 1/2

Journey
And I really liked FAR : Changing Tides and FAR : Lone Sails

The newest ratchet and clank was a try short but fun play through

two pages and no mention of outer wilds

@op you on PC?

No, only ps5

Outer Wilds is peak puzzle/adventure game

any saints row game

I would give everything for a sr2 remaster. Ffs just give me a decent port I’ll take anything

Return of the Obra Dinn

Vanquish

Bayonetta

Limbo

Pentiment (could take more or less than 15 hours depending on what kind of reader you are)

Katana Zero. 5 hours of samurai action, a story where your decisions hold weight, and peak pixel art

One of the best games ever

resident evil.

for anyone on Xbox, sunset overdrive

Mafia 2 felt like no filler

Missions because even more engaging as it went on
