The people who complain that the nights are too dark must have never been in the wilderness on a cloudy night. It can get literally pitch black, so dark that you can't see your hand in front of you. That is one of the reasons you need campfires, to know your surroundings. This is not your average shooting gallery where nights are like day with dark filter, the sooner you realize that the better. That said, it would be appropriate with some lighting from full moon, to make it realistic it should really only be so that you can barely make out sillouettes, anything else is too much.
