Games you have completed in one sitting

[Harlemura]

Sonic 2, but that's kinda cheating because you can't save games on it.
I might have beaten Crash Team Racing as well, but I can't remember. I got to the last world part at least. That was years ago though.

 

[quiet_samurai]

Portal. I got it on steam at midnight the night it launched, and stayed up until about 6 in the morning. I wasn't even planning to do that, it just happend.

 

[Canadamus Prime]

SMB 1-3 & Super Mario Land.

 

[Always_Remain]

Portal.

Halo 3.. oh fuck. don't remind me.

Oh yes and I don't know if it counts but when I got Mass Effect 2, after I played it for a few hours I stopped. Slept. woke up. started playing it again. 7 hours later i stopped again. slept. woke up. started playing again. 14+ hours later i was done. 35 hours in totally. kinda rushed i guess.

Bayonetta and possible the entire dynasty warriors series you play one conquer enemy fields mission you have played them all just change character design from feudal japan to giant robots occasionally, feel free to correct me if i am wrong about the series

 

[Seef]

Only Portal.

[MicrosoftPaysMe]

spent a whole day doing this.
run through, halo 1 to 3. and you realize, that you have no life when you do this that the SMG in halo 2 was technically the assault rifle. just made smaller, and weaker. i played this game on the hardest difficulty, (legendary, until halo 3, i threw mythic on for S & G's.) whilest trying to kill everything. good times.

I did that but in 3 days 1 game a day

 

[JackalSick6Sick]

[Aurora219]

All of the Half-Lifes - including the first one and the episodes.

All of the Halos - first one was the most arduous, ironically.

Hitman 2 and every Hitman game since (Contracts, Blood Money). Not as easy as some games..

The singleplayer campaigns on Red Alert 2, Yuri's Revenge..

I tried once to complete Age of Mythology all in one go. 18 hours later I keeled over and fell asleep in my chair..

Oh! And I once completed One Button Bob in one go too!

EDIT: Oh, yeah, Bioshock, Gears 1+2, Mirror's Edge.. feh..

 

[CaptainFatty]

I finish most shooters in a single sitting. The Halo series, Both Army of 2 games and almost every CoD game.

One I'm not proud of is Fallout 3. Woke up, started playing, ate once then finished the game and went to bed.

 

[Bilbo536]

You my friend are thinking of Mystical Ninja!

 

[PrimoThePro]

I did that but in 3 days 1 game a day

see, now, that would be sensible.

 

[Composer]

L4D1 each campaign took 1 hour

 

[FrederickPlus]

Do fighting games count?

Mortal Kombat(s)
Street Fighter(s)
Alex Kid in Miracle World
Portal
Golden Axe
Double Dragon

Admittedly most of these games cant be saved, so they have to be finished in 1 sitting. =P
