I was just thinking about how much serveral of the games in the FF series likes to use the oceans, and the earth, and even the skies as major Thematic elements.

For instance FF 7, is incredibly reliant on the earth, dealing the lifestream and how that is tied to every lifeform and even Mako Energy.

FF 12 is heavily dependant on the skies, with floating cities, towers that extend into the heavens, etc etc.

FF 10 however is extremely sea driven. Sin is the ocean. Lots of swimming, underwater scenes, crossing the seas on boats for extended periods of time.


Obviously each game uses these elements to some degree, but what do you think about other games and the general idea of themeing around these elements? Is there another element that could be included?
