Portal when I was bored one day. Usually however I hate doing it one sitting, if you pay for a brand new game, it sucks if you complete it in one day.

 

[Dr. Win]

Solo:
Portal (Duh)
MW2 (Hardened, I got halfway through on Veteran in 4 hours then went and played multiplayer)
The Half Life 2 episodes.

Group:
During the last Christmas holidays me and some friends did a 24 hr non-stop playthrough of all the main Assassins Creed games (1, 2 and Brotherhood). Took us about three days. Fun Times.

 

[SpireOfFire]

halo 3 and the force unleashed 2.

- Many Flash Games.

 

[A Raging Emo]

-Halo 3
-Halo Reach
-Gears of War

And I didn't do it initially, but I have finished Oblivion's main quest and Fallout 3's main quest in one sitting.

 

[Woodsey]

Splinter Cell Conviction was the last I can remember I think - such a waste of potential.

 

[TheFinalFantasyWolf]

MGS 2
Shadow Of Memories
Wanted
King Kong The game (*sigh my lil Bro liked it and just likes watching me play, thats why -_-)
Prototype
Crash Bandacoot
Super Mario 64
Modern Warfare 2

 

[the_hoffs_ego]

Modern Warfare 2 and Black Ops campaigns

MW2 because the server went down on PS3 within the first 24 hours of it being out... and Black Ops because I quickly got bored of multiplayer.

 

[WoodenAshtray]

- Portal
- Modern Warfare 2
- Bulletstorm

..Not really a whole lot, I usually get bored of a game after playing it for too long. For example, I played 10 hours of Darksiders without taking any major breaks, and then I didn't play it for like 2 weeks.

 

[Richardplex]

portal 1+2, l4d, mw2
Ratchet and Clank 2, 3, gladiator & tools of destruction. didn't do quest for booty in 1 day /ashamed, probably could do a crack in time but that makes me cry when I remember the older games so I haven't managed it yet.
spyro 1, 2 and 3

Most games I play are long because I find them more immersive that way, and that's why I play games, games from my childhood which are still amazing today, or multiplayer games. Portal 1 excluded, but not portal 2's, because the coop > SP.

 

[silasbufu]

Only Call of Duty World at War, because I played it with a friend online and it was really short. I'm really not that ambitious / addicted or whatever makes you do stuff like this.

 

[Cridhe]

Megaman X
Megaman X4
Super Metroid
Super Mario 3

Those are the most memorable to me. I swear I could have won an award for my Super Metroid speed-runs when I was in my prime.

 

[Cridhe]

Only two I can think are Black Ops, I probably wouldn't of completed it otherwise dear god that was a confusing mess of a campaign and condemned criminal origins, in the dark whilst being the only person in the house, not my best idea I will admit but it certainly added to the atmosphere.

Not much to say here except kudos on the awesome avatar.

 

[Stuntcrab]

- portal 1
- portal 2
- half life 2
- red faction Armageddon
- Dead space 2
- modern warfare two

Yep those are them, there are probably more ill think of some later.

 

[Watson767]

Final Fantasy 7. 9 hours. Pretty gash :/

 

[UnderCoverGuest]

Portal and Duke Nukem Forever.

 

[2ndblackjedi]

The only game I've ever finished in one sitting was Ratchet: Deadlocked because I had lost my PS2 Memory Card at the time.

 

[zelda2fanboy]

Star Fox 64, Full Throttle, and Jet Grind Radio on the Dreamcast. I had a sick day and just sat down and played it beginning to end.

 

[100tacks]

I try to avoid finishing a game all at once. I think the only thing I've beat in a day is Sonic 2 on Genesis.
