There should be an option to simulate the climate on non-Earth planets (As in, randomly generated planets). On a planet with atmospheres and water, ice caps would form around the poles, and it will grow or shrink depending on the season, which depends on its axial tilt/obliquity. On a tidally locked planet with atmosphere and water, the side that is facing the star would dry up, while the side that is facing away would freeze, kinda like this :

(Sidenote : the hurricane is optional)
