Games you finished in one sitting

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

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.
