Suggestion: set servers to June 23, 1995. I was fiddling around with various dates in the editor, and found that was a evening with a full moon all night long, and a fairly short night (since it's near the summer solstice). The full moon results in a graphically pleasing environment, while still presenting significantly distinct game play from daylight. Furthermore, the game is still quite playable (at least it was for me) when cloudy, presenting a third interesting environment. I understand the desire to have fully dark nights for everyone. I would support them... if they were technically feasible. But because of the ability to set gamma preferences, there is no way to ensure that everyone will have darkness. One can personally handicap themselves by refusing to change the gamma, but this won't really result in an authentic experience, as one might very well find oneself randomly shot by another survivor who is abusing gamma. It is interesting to stumble about in the darkness, knowing that everyone else is stumbling about as well. But it's significantly less interesting to stumble about in the darkness, when virtually all other players can fairly easily see you and shoot you in safety, and knowing in the back of your mind you could level the playing field with a couple of clicks.
