The longest game you've beaten start-to-finish in one sitting.

[Retal19]

Dragon Age Origins. During German class my friend told me it would be impossible to beat it in one sitting. I turned to him, and said 'Herausforderung Angenommen', German for 'Challenge Accepted'. I think. My German isn't the best.

And I did it, barely. The only thing I was mad about was that I wasn't signed in when I did it. I realised that in my rush to get through it I had simply skipped right past sign in and straight onto a guest account. Still, at least I know how to do it again on my account.

I died like 40 times in that playthrough, most of those times at the final boss, but I refused to turn the difficulty down.

I had two such outings on two different weekends of summer when I was doing the school thing.

Grandia 1 - Played for 54 hours without sleep

AND

Final Fantasy 3 (US number) - Played for just under 60 hours without sleep, and got all the way up to Kefka with Gau only missing either two or three Rages.

God i miss those days...i remember playing KotOR for the first time in one far, far beyond awesome start-to-finish session. Two days later i was stealing The Sith Lords from a friend.

Honorable mentions go to Rome:TW & PvZ.

Also F.E.A.R 2 and The Godfather...don`t ask me way.

 

[TilMorrow]

TimeSplitters: Future Perfect. Played through the game the in 2 days then came back and completed it in 4 hours.

Portal, HL2, EP1 and EP2. At least took from 3-4 hours to complete.

I played through all 6 Gold Label Forgotten Realms games (Pool of Radiance, etc...) in one sitting when I was 18. Took me about 70-90 hours I believe.

Completed a playthrough of Civ 2 in one sitting. Won by domination by 1600AD on Prince setting.

Played Oblivion for around two days when I first got my 360. Fallout got a similer treatment as well. Neither were completed owever.

Not sure if it's necessarily the longest, but I recently kicked the ass out of Mass Effect 2 in one sitting. Not 100%, but I did side missions when I could find them.

 

[Dr. Win]

AC2 and ME2 in one sitting.
I didn't get 100% completion though, just finished the games.

 

[GrizzlerBorno]

Medal of Honor (2010)
Don't look at me like That! I probably liked it a LOT more than the average gamer because I played it in one go. So, yeah, it was a good, though not great game.

 

[black-magic]

GoW 2

 

[Helmet]

Prince of Persia (2008) and the DLC. Took me about 10 hours, ignoring the collectibles.

 

[Onyx Oblivion]

Maybe Halo 3's campaign in co-op. Maybe.

 

[Asuka Soryu]

I beat a game of Yu-Gi-Oh! in 1 minute.

 

[Rhiehn]

Mario 64, admittedly, it only took like 30 minutes.

 

[Chibz]

Desert Bus, almost did a three way trip. If you knew how much endurance that took, you'd worship me as a living god.

 

[Faladorian]

Metroid:Fusion
Assassin's Creed
Pretty much every gameboy game except Zelda Oracle of the god damn Ages
Warcraft 3
Super Mario 64 DS
Portal
Half Life 2 (I think...)
Half Life 2 Episode 1 + 2



I mostly play RPGs, and like a previous poster had said, If I beat an RPG in one day, I wasted my money.

I play RPGs. If I can finish an RPG in one sitting, I wasted my money.

QFT.

 

[Lineoutt]

I do not have the attention span for that lol, I wish.

 

[Grey Warden]

Dragon Age: Origins. Did every quest in the game over a twelve hour span.

 

[Electric Frederick]

Longest? when i was 11 i beat Halo 2 in one sitting, about 12 hours. But i never stay on one game without taking a break.
