Longest You've played a game total without realizing.

[PPB]

I've done some straight 10-12 hours of WoW for a dozen consecutive days. The "funny" thing is that I've actually never been that obsessive about the game, but back in summer 2006 I happened to have absolutely nothing to do for a couple of weeks and just stayed home and played. That was right before University started, and I figured I might as well tire the gamer in me a bit before jumping in =P

Other than that I've also done some 6 hours-ish periods of Baldur's Gate, Diablo 2, Morrowind, Oblivion, Knights of the Old Republic and Neverwinter Nights. I love RPGs.

Overall though, WoW is by far the meanest game as far as time sinks are concerned. It's been a while since I played, but I remember that an hour of WoW equaled around 15 minutes of my internal clock.

Once I sat down for a quick Pirates! game. After what seemed like 2 hours, it seemed the sun had set and risen again.

My parents were out of town, I played Mass Effect for three days straight(minus toilet/food/water). When they came back I saved it, turned it off, and slept for a day.

Best snooze I've ever had.

Ohhhh you must've been a smelly little hobbit by then!

Mine would probably be FO3, I dedicated a weekend to the completion of it.
1.5 cases of beer
3 frozen pizzas
2 Litres of Coke
1 Fallout 3

Clocked up;
7 hours on Friday Night
10 Hours on Saturday
8 Hours on Sunday
- Give or take time for toilet breaks etc.

Had to train hard to get rid of my Fallout flab the next week.

One time at D&D our party played for 19 hours straight.

p.s awesome avatar, I'm starting the last book but it's kinda lost its charm since he started bringing reality in to the fantasy mix
