Guild Wars 2

So a few friends of mine got to think that since this game has a day and night cycle it would be pretty cool if you noticed that more.

as an example making night time dark as in the ice fractal after you kill the elemental. its light enough so you can see but still also dark.

people would turn up gamma at night and it would make firing siege in WvW ridiculous. It would be cool but most people would hate the change.
