What Is The Most Amount of Time You Have Played a Game(s) in a Day?

[bluster]

I beat WindWaker in a single seat back in 2003. It took me from Saturday 10 AM till Sunday morning, allmost a full day.

I also finished Paper Mario GC in a weekend, tough that was not a single session

I also remember that, back in 99, when I was twelve, my mom bought me a GBC with Pokemon Yellow (the Pikachu Special Edition) and I spent all the night playing it, trough Kogas Gym. That was really adictive.
I remember that, when I finally got to bed, with my eyes injected in blood I could still here the damn MIDI inside my head.
