This game will be fantastic, I guarantee it. It will have a rich story, some epic plot holes, beautiful environments, awesome characters, an amazing soundtrack, an encouraging battle system, and a bucket full of references to earlier entries in the series.
BUT! All that doesn't matter since fans will destroy it anyway for not being like their favorite Final Fantasy game. At this point, no matter what SE does, nothing will please them all. Everyone and their mum will step up, declare himself as FF expert and discuss in page long comments why this or that is bad and why this or that was so much better in [insert random FF game here]. I mean, seriously? Why the heck do we need to complain about an all male party? Who cares? As long as the game has lots of other female characters, why the outrage? Why not accept what the designers are trying to tell you in the way they seem fit?
The FF fanbase is sooooo divergent, SE should just close eyes and ears and do whatever the f they want. Just release them games, we'll buy 'em anyway.
