Games you finished in one sitting

[iDoom46]

Portal, Modern Warfare 2, Halo 2 story mode, Super Smash Bros. Brawl story mode, Pokemon Snap, Left 4 Dead 1, Dead Rising 1 (non-story mode), and the most recent Prince of Persia reboot.

I could also probably get through The Legend of Zelda: Ocarina of Time in one play through if I cleared my schedule for a day. I played through that game so many times I pretty much know all the dungeons by heart.
Yes. Even the Water Temple.

 

[Locko96]

Portal and the COD games. I'm waiting for someone to say KOTOR or Mass Effect.

 

[lobster1077]

Rogue Warrior. Worst game I have ever had the displeasure of playing. 2 hour campaign, suckass story, dialogue, gameplay, and graphics for $60. I will never buy another Bethesda game again.

It's a total goatfuck!!

 

[DangerFish]

metal gear solid one
it had to be in one siting because I didn't have a memory card

 

[Philip Preeo]

Halo Reach, Heavy Rain, Mass Effect 2, Duke Nukem: Forever (not that I found it wholesome).

 

[A Weakgeek]

Portal and I guess Left 4 dead if beating 1 campagin counts.

 

[OpticalJunction]

Portal 2

 

[The Cheezy One]

Devil May Cry 1
Lord of the rings, two towers

Both fairly good games, but didn't take much of a pounding to get through

Left 4 dead if beating 1 campagin counts.

I don't think so, as you don't have much choice. You can't load into the middle of a campaign unless you jump into it online, in which case you haven't done all of it.

Every modern military FPS, because they're so god damn short.

They may be short in relation to other games, but if you can pull 6 hours out of your day, I would be impressed. I don't have that much free time any more!

(Waagh power! For the Imperium of Man!)

medal of honour the i think pacific one on the playstation. the coop campaign.

most games i play go for 20+ hours so not many i play in one sitting.

 

[Lilitu]

Limbo
I didn't know how to save and it was so thrilling that I couldn't stop and always wanted to know what comes next.

Vampire Hunter D (PSOne)
I think I finished this one in one setting, too. It was a really short game.

Usually I play quite long games.
btw: 200+ hours was the longest time I spent on a game. I think it was Final Fantasy XII, Final Fantasy VII didn't count further that 99:59:59

 

[mikey7339]

The only one from recent memory is Homefront. My friend loaded up a new game to show me and we ended up trophy hunting and beat it in like 4 hours. I heard the game was short but my god...

 

[Lord Beautiful]

Castlevania: Symphony of the Night

The game is surprisingly short.

 

[KaizokuouHasu]

SNES: Donkey Kong Country, Super Mario 2 and 3
PC: Portal, Half-life 2: the chapters, Deus Ex 1
Xbox: Fable 1
X360: RE5, Halo 1-3, Left 4 Dead 1&2,
PS2: Resident Evil 4 (easy, no cheats)
PS3: Little Big Planet

Can't remember the rest.

 

[Pandaman1911]

Portal, Portal 2, StarCraft II (Jesus christ that one took a while), and... can't think of anything else.

 

[Fetzenfisch]

Kirby's Dreamland
Left for Dead
Tekken 3
Spider Man (NES)
Darkwing Duck (NES)
Super Star Wars 1-3 (snes)

 

[AlmostLikeLife]

Portal (my second playthrough onward)
Portal 2
Call of Duty 3
Call of Duty 4
Psychonauts
The Suffering: Ties That Bind

There are probably more that I just can't think of right now.

 

[Mr Fatherland]

Rogue Warrior. Worst game I have ever had the displeasure of playing. 2 hour campaign, suckass story, dialogue, gameplay, and graphics for $60. I will never buy another Bethesda game again.

Not even the Elder Scrolls or Fallouts? You my friend are missing out.
