Gaming into the Wee Hours

You all know the feeling: you're playing ________ and you/your character just reached level 15 and the game is finally picking up. You're getting your new powers and the plot's really starting to develop. But it's 11 PM. You promise to cap your gaming at 30 more minutes but in an hour, you just had your first face-off with your central antagonist and this cutscene, no, you just can't skip it. So you keep playing, you keep playing until that LCD clock beside you is reading 11:00. AM.

The question is to what extent have you ever done this? My most recent experience was with Knights of the Old Republic 2. I'd been playing it on my 360 and ever since it started getting more exciting with the force powers, I pretty much plowed on through regardless of time. I found myself going to bed at 4:30 AM.

The funny thing is I know so many others are going to outdo that time so shoot.

Jam it back in, in the dark.
