Why would Falmer have torches? They are blind.
To cut it short I think there should be underground areas (or even interiors of some buildings) where it is completely dark and you have to use a torch or soemhting like that. I would add a degree of realism to the game as well as make the player more suspectible to ambushes 'n' stuff. There's not many things that get your heart racing than being in a dark tunnel when something like a frostbite spider jumps up on you.
So what are your thoughts. Do you think that there should be some areas of darkness or would it ruin the game?
