Daylight/night time does add (although, I usually sleep at night in games that offer it). It's especially good if you are playing an assassin type character. I've yet to find a game that handles food well, though. Most use it for healing wounds. I'd prefer to have a player lose attributes if they don't eat routinely with especially harsh results for not drinking. Really adds to long trips in the wild or especially a desert environment. I wouldn't mind seeing the possibility of buying pack animals or wagons for carrying a lot of supplies. It would add strategy since these things would have to be guarded and even opening side quests of finding and dealing with the thieves. In this game, I don't even bother with food - I just sell it after making it more valuable with cooking (although I never did the math to see if that is a waste of time).
