Gh3 9 hours I guess. I'm sure i'll beat that time in February though.

Me and my cousin once played Gears of War for almost 8 hrs. I usually can't game longer than 3 hrs at once unless I'm really enjoying the game.

lanparty 36 hours, we played CS, COD, UT, Starcraft, COH, some of us went to sleep in bgetween I wasn't one of them.

Super Smash Bros. Melee- 6 hours.

Hopefully that record will be broken by Brawl.

I think I played Oblivion one day for about 5-6 hours straight. Damn that games addictive.

Around 20 hours, i have done this with lots of games.

Probably some RTS game, hours seem like minutes when I start playing those... Warcraft 2 would be a good bet.

Outside that genre, I must have passed some many whole afternoons playing the original Quake.

Lego Star Wars I - 10 Hours cooperative with my cousin, from 8PM to 6AM

WoW, a whole frickin 24 hours

Did you die afterwards, like that Chinese guy?
