In most Video Games time seems to be based around the main character's progress, rather than any sort of actual time. This leads to the Fridge Logic of you apparently going through an entire night in the course of a few hours. This also goes the other way in that if you stay still for several hours nothing will change at all. Very much among Acceptable Breaks From Reality, as the time of day has an large effect on the mood and atmosphere of specific scenes, along with the massive technical difficulties to which the alternative leads.
