Besides, the vague stuff I've heard about these "spoilers" doesn't address half of the teases given about XV's story by the developers themselves, and it just doesn't look anything like Final Fantasy in any form. Without going into specifics, it just sounds like some weird fanfiction dreamed up by a disgruntled person, combining elements from earlier games into a screwy mishmash.
EDIT: On a happier note, I'm looking forward to seeing what kind of trailer they create for E3 2016, and what form their playable version will take (hopefully it's not Duscae again, but something more advanced).
