I'd rather just the night and day thin add a visual aspect to the game, perhaps adding advantages and disadvantages based on visibility but not stuff like "The Werewolf is strengthened by the moonlight, granting him 50% more awesome" maybe this werewolf example just sees better in the dark than others,but that's it. Other than stuff like that, a night time map could have a lot of fun visual effects and strategies. I could just imagine half the map being set alight by the torchbearer, casting an orange glow around the entire map. It would be REALLY interesting if seeing a bright light at night affected your visibility the way it would in real life, IE: Rook's tower of light attack thing causing serious blinding and disorientation to the minotaurs below.
