Whats the most amount of time you've played through a game without taking any breaks?

As for myself...it was about 7 hours playing through the entirety of Heavenly Sword.

My total would probably be 4 hours or so. Not that impressive.

4hours after that my brain go numb and I must stop to recharge it

Hmm...without taking any breaks (including bathroom breaks)?
I guess it would be 12 hours (I was playing 3 games alternately and I completely forgot the time)
i was extremely hungry after that >.>

gears of war 2 (first day it came out) 7 hours. got up to the 4th chapter.

Probably FFX, from like 6pm (after dinner) till 3am...the story was that engrossing, so that was 9 hours. That was Summer 2003 when I was 15.

DMC runs a close 2nd. I beat that game all in one go back in October 2001 before I owned a PS2. I rented a PS2 along with DMC when it came out and I didn't have a memory card. So I beat it all in one day, only taking one 30 minute break for Dinner. I started at about 1pm after lunch and finished around Midnight. I would have been 14 at the time, as it was October 2001.

There have been various other games where I have done 5-6 hour sessions, such as Kingdom Hearts, Xenogears, other FF's and other RPG's. I also used to have long sessions with Brigandine.

i remember playing majoras mask for 16(maybe 18) straight but i did take a couple emergency bathroom breaks.

5 Hours on Final Fantasy X and VII. I was never doing anything on Sundays so I said what the hell and Popped them in

My friends and I woke up at 8am to play Nightfire on the PS2. We played a CTF game with the first to 50 points being the winner. We didn't stop until 4pm in the afternoon.

I also think there were a few times where I spent 4 hours just playing Triple Triad in FFVIII. I had a similar thing with Blitzball in FFX, but that was usually around 2.5 hours.
