I would have agree with tyrano man. I don't like games that go totaly black. While I can see the use for this occasionaly, it just doesn't seem to serve any purpose in most cases. I mean if you can't see anything, what is the scene for? I like it so that when you get right next to something, you can just make it out.
FPSC lighting is not realistic, as well. If you make a hallway and put a number of small range lights down the side wall, you still get black edges at the bottom of the walls and floor. A match would spread light more evenly than the FPSC lighting.
This is of course a personal preference and dependant on the game. If you need pitch black areas in your game, then you'll have to light everything else that needs to be seen, even the slightest bit.
Best.
I'm sorry, my answers are limited. You must ask the right question.
