Lighting in games works on 2 levels. There is direct ligting, the one that have a visible light source and cast shadows. But the is also a default luminance across the entire game, this is then multiplied to create day/night cycles. But it's always there, all the time, effecting every surface in the game irrespective of whether it is 'indoors' or not.
the answer would be to create a shell/bubble in which the default luminance was permanently multiplied by 0.0001 (effectively zero luminance).
I definitely agree peeps should experience heightened excitement and intensity in the dark. The zero light 'bubble' could trigger that in fact (perhaps all default excitement and intensity multiplied my 1.5?)
