Project Fog provided a lot of the inspiration for this. I just find it interesting that the lighting effects can also be played around with to create visible "shadows" when done right, for atmospheric effect.

But rather than have it everywhere, I believe that instead structuring Set Light and Trigger Zone events to turn everything on and off at appropiate times works better in practice, which is also important due to the limitations of how many events can be in a single player level before problems start arising (if I recall correctly).
