What's the longest time you've ever gamed in a single sitdown?

12+ hours, but never on a single game. Last time i did that was years ago when a friend came over, we rented 1-2 games, and we played like 4-5 of them from 8 at night till 8 the next morning.

I've done 6-8 hour sessions on various other games, but not typically. Typically my max is 4 hours.
