Just what it says on the tin. Obviously most characters from the NES generation are over-the-top fantasy. Locke from VI is probably the least fantasy-oriented. And then there's IX.

VII, VIII, XIII, and XV pretty much have entirely modernized characters. I'm not sure where to put XII and Type-0.

Out of X and X-2... I don't know, the main characters are islanders in a revitalized PA world. To me, Paine is the only non-fanciful character.

As to that, what is your preference? Should Squenix keep on with their trend of post-modernized, futuristic, omnipunk setting? Or do you want the dragons and griffins to be fought by actual armor-clad dragoons and knights? And kings clad in purple and blue with red capes...
