Fucking seriously. It's such a ethereal, ghostly approach to art... brush strokes bleeding into one other, with an effect like percussion. I don't mean to pontificate on the art, but one of game's primary purposes is to transport to world's unseen, and his is so eminently unique, so evocative and surreal that (for me at least) it's impossible to not want to uncover what dark secrets may lie within.
It's always been one of the most disappointing things to me that with next-gen power, Final Fantasy hasn't tried to move back in this direction more vividly...
