I think the darkness is great, and most certainly terrifying. I'm always able to distinguish the sky from anything on the ground (treeline/building outlines etc.), and while everything is indeed pitch black, there are torches and flares and whatnot (to use at your own risk!). From what I've played so far, the night time is an entirely different experience to the day; one that strongly encourages teamwork with other players, and somehow always brings people together by a flare in desperation to survive. Nobody wants to be alone in the middle of a zombie infested village! My only thought is that night time perhaps lasts too long, and that rather than 24 hour clock, perhaps it could be 12, or 6. That way everyone could more easily experience the transition from day to night, and the glorious feeling it must be to see the sun rising over the horizon after a night of survival. Damn, I haven't been on Day Z for more than 24 hours... I seriously need a fix.
