I'm talking no real breaks other than restroom breaks. What's the longest you've ever gone on any game in a single sit down? Most you've ever played in a day? For me it was a memorable Christmas many years ago. I had gotten Medieval II Total War recently (not for Christmas though). I ate lunch at my grandparent's house in town, hung out there for a while, then went home around 3pm and fired up Medieval. I played and played, got hungry and found some biscuits sitting in a bag and ate them while I kept playing. Next thing I knew I looked up at the clock and it was almost midnight. Share your stories. I'm guessing quite a few of you have gone longer than 8.5-9 hours.
