Nighttime after all the kiddies go to bed is the only time I have for interrupted play. As for playing until 8am, usually not (it has been known to happen on occasion). Most of the time this happens when I get to the final area in a game (most recently it was Ultimecia's Castle) and I think, "oh it just a few more bosses and then I'll finish the game." And I do, five or six hours later.
