We always see "Favorite" or "Best Game" or whatever, but this is something different, which game of the main series best lived up to the term 'fantasy'?

Personally I have to give this one, to FFXII. On first glance, I was worried that FFXII was going to revert back to the VII and VIII definition of the setting of an FF, some futuristic crap-hole, because the very first thing I saw was huge Star Wars-esc, ship battles. Once I actually got into the game, this changed. From the deserts of Dalmasca and the pure foreign look and idea (a mine in the sky?) of Bhujurba, the entire game really gave that fantasy world effect. It managed to tie in so many different types of scenery and places, both in and out of this world.
