I'm not saying that you can't think of your interpretations as correct. But, interpretations are just that, interpretations, possible answers but not definite answers. I'm not saying that my interpretations are correct either, I try to prove them as correct, yes, but even so, mine are just interpretations, so as yours, wether they are correct or not, we might never know.

I don't have such regard towards Nomura, I even think that this FFVII "sequel" was too much for him, but I do think that he has a little of seriousness, so as Nojima, to write a real plot.

Oh yes, this is the quote I was talking about, it came on the Newtype USA October issue:

To this day, FFVII continues to draw some fire for its ambiguous ending. It's a satisfying conclusion [and beautiful to behold], but it doesn't hold the player's hand through a lengthy denouement the way 16-bit Final Fantasy games do. That shift in presentation, Tetsuya Nomura insists, was entirely intentional-- the goal was to make players think a little harder and pay closer attention to a more complex storyline. "I don't know if you could really say that FFVII had any unanswered questions to speak of," claims Nomura, taking what some of his fans [or detractors] might characterize as a slightly controversial stand. "We just created FFVII with the idea that we wouldn't just come out and tell people the answers. The answers are there, but no one is there to tell you where to look for them. We didn't leave anything hanging." Nomura, of course, had the advantage of the original game's scriptwriter sitting across the office to point out where to look. But, on the bright side, if Square had spelled everything out, there might not have been enough demand for a sequel like Advent Children.
