In almost every KQ game--with the exception of KQ4--it is perpetually day time. You can have the player character stand there for hours and it will still be the same time. I always thought this to be a flaw in the series. While I don't think that a day/night cycle should be timed out--like, have to do with puzzles or events (ala QFG), I do think just having the day slowly transition from morning to afternoon to night, and perhaps adding in an element like a KQ character having to find a place to sleep or something during the night, might add a more modern touch to the games. You could even have it be slightly like KQ4 in that certain things or certain characters can only be met at night or something. I just think it'd be a nice touch.
