I watched a live streaming of it for a little bit. One thing I can say is that this game will have more lyrical tracks than any other FF game to date. They also seem to trade in exploration for narrative.
having a pretty boy evil guy who we think he's dead early in the game just to discover that he's somewhat alive in a larva state inside a crystal and that he plans to absorb all the power of the Lifestr-I mean, the Fal'Ciels to become the ultimate godly entity who destrys the world and reshapes it to his liking
? It's not a real spoiler, just my guess (and I really hope I'm wrong)
