Longest gaming marathon you've ever had

[Scorpion]

What's the longest gaming marathon you've ever had, and what game kept you hooked?  

Mine was a 72-hour World of Warcraft marathon.. leveling my first character to 60 was addictive bliss...

I'd say a 24 hour one and it was Grand Theft Auto: San Andreas on a Saturday. I basically played the whole time with a few breaks in between for food and bathroom use.
