Well, if you're including time of day and weather, you might as well create seasons to go with it. And everyone knows, if you have seasons, you have to have festivals, birthdays, things of that nature. Maybe a character gains extra stats, fol, and exp on their birthday. Seasons would also give you a greater expnse for the AWS. Snow would appear in the winter month, but rain the others. Things of that nature. FFXII did that, for 2 or 3 areas. haha.
