I'm sorry, but I could only have one reaction to this :
Is it a good idea to survey the fans to decide upon a direction for a franchise? Sure. Will Square Enix act upon the feedback they receive from those fans? I don't know, but at least they asked , so here's hoping the Kingdom Hearts franchise will benefit in the long run. I'd like to assume that the KHIII developers know what they're doing.
What's so infuriating about this poll is that I don't recall ever seeing any such survey for the once-revered Final Fantasy franchise. Years of decline and all we ever heard was that Square Enix acknowledged the backlash; there's zero evidence of that acknowledgement in recent FF titles, but whatever. I really don't remember ever seeing a survey like this and if such a survey did exist, I can almost guarantee I could've predicted the results and hence, Square Enix flat-out ignored them.
What I want to see now is simple: Just do the same thing with Final Fantasy . Hold a Facebook survey for that franchise and see what happens. After the world exploded with frustration and bitterness, maybe then they'll figure it out. Maybe.
