I got an idea!
You know how we have a screensaver for the Windos version of Fish Tycoon? How about having a screensaver from Village Sim, but is shows the village at night? So there would be a camp fire, a few villagers dancing, light in the windows of the huts, some jungle-drum music and water lapping on the shore.
No need for there to be a day/night cycle in the game itself then.
