I.e., games that hooked you in and you couldn’t stop playing until it was finished. Not games that just happened to be unexpectedly short. And by “completed” I guess I mean the main story etc, not 100%ing the game :).
For me, it would be Catherine, Bioshock Infinite and Black Mesa (although I think I got to the final area then had to go to sleep and complete it the next day). I also played an ungodly amount of Hades in one sitting, but didn’t get the “full” ending in one day.
Inside!
I also completed bioshock infinite in one sitting with my brother when I was younger. That shits a core memory for me now lol
Stray.
antichamber literally kept me up all night until I finished it at 9am
Carrion. I was surprised how much fun it was. There’s some nice but not overly difficult puzzles and some frantic bursts of combat
Inmost - short platformer/metroidvania game with a brutally emotional storyline.
Far: Lone Sail - short puzzle/platformer game. Chill as fuck, great atmosphere and music. Story is only really gleamed from the environment that you traverse.
Return of the obra dinn. Both because it’s good and because I was worried my train of thought would be interrupted if I took a break. Took me ~9 hours and gave me a really bad headache afterwards, no regrets.
Portal 1
super metroid and metroid zero mission. Man I love those games.
Cataclysm Dark Days Ahead. Because I usually die in like the first week in game lol
I wanna say Yoshis Island for SNES but it was so long ago I don’t remember if it was one or two sittings. Dunno about the “that was so good” part though. Just completed it :)
Spec Ops: The Line. I started playing it in the morning, the story kept me engaged (and the gameplay was fun enough). I played it all day to its conclusion.
Ironic!
Why?
Because it’s a game that’s constantly telling the player that they should stop playing it. That everything is going to get worse if you do and it’s all your fault. That you’re going to cross the line again and again and again until every single person in the game is doomed. And then we play through the entire thing anyway, because it’s so fucking good.
Max Payne!
Plants Vs. Zombies!
My wife and I just sat there like… zombies… for the whole day and night until we finished it, and then went to bed surprised and happy when we got our musical reward at the end!
The Flash gaming era at it’s best.
Sleeping Dogs pulled me in real hard. I‘m super salty there‘s no Sleeping Dogs 2, I loved everything about this game.
If any of you like GTA style gameplay, Sleeping Dogs is that plus kung fu movie flair (even has a cheesy king fu story DLC).
Nioh, Nioh 2, Code Vein, Dark Souls 2 (I know), Fairy Fencer F, and Ni no Kuni 2 also put me in chains. Crusader Kings III has no real story but it made so many evenings disappear that I try to legit stay away from it lol
