Well seasons are just a thing that someone decided to label the months and whatnot :/ If that someone had lived somewhere that didnt have all four seasons then it would just be that much more different...
Hmm here the four seasons... summer = fog fog fog clear fog and fog~ winter = clear skies but freezing... spring = rain rain rain rain fog rain rain sun rain blah blah... autumn = a mix between the three depending what part of the month it is :/
You rarely get a good film adaptation from a game.
Especially when the game is longer than any standard movie. Picking parts will mean that a lot of the story will be cut off, sometimes even the important areas left unexplained.
