Square has ever been the pinacle of storytelling and emotional rollercoaster throughout every game. I played all Final Fantasy I-XV and I got to say, I expected more from an MMO based on the game.
My main gripes are this....
1. storyline, there is no real "red thread" about this all, it is an endless amount of "go there, do this" and it does not connect togather in a good way.
2. emotional attachment. SE use to rule the world with the storytelling, Opera scene in FFVI ( https://www.youtube.com/watch?v=hgZXiHfNt0M ) and the ghost train, and this ( https://www.youtube.com/watch?v=DLCE6xQEXoQ) it is awesomeness, and this is only a mere fraction of the events. In the MMO there is no such thing, there is an detachment between the hero and the storyline, there is no real emotional bond.
3. Voice acting. That is among the BEST ways to give a story life, need MORE voice acting. and FMV, Final Fantasy games use to be famous for their FMV.
