I'm a marathon gamer. I recently replayed Still Life and it took me two days, with probably about 8-10 hours straight on the second day.

Some games get too annoying after a while, but a game I really like, especially a replay will keep me glued to it until I have to stop for sleep or work. I'm that way with the Phoenix Wright games, too.

I remember playing each Tex Murphy game for whole afternoons/evenings up to 4am on a few occasions before my whole body complained and made me sleep. Stupid body. :P They just captured my attention so much I couldn't stop playing, same for Deus Ex (that's part adventure right? :P).

It took essay deadlines to stop me playing Overseer so much. No other games have captured my attention so much before or since. Loved them.

I have to be careful not to start a game when I have other committments going because I tend lose track of time when playing. If my husband calls me for dinner, he knows that grunts or uh-huhs do not necessarily mean I've heard him on a conscious level. I've been known to play 8-10 hours straight, but, like Colpet, I stop when my brain gears start spinning unproductively.
