I don't really mind the recycled appearances,I just hope they don't also recycle their personalities or abilities.Since they are his creations I believe he can decide whatever he wants,maybe he just did that on purpose so we don't forget the characters of past FFs.

As important as the storyline is though, we have to take into consideration that we're talking about a series which atleast since Final Fantasy 7 has relied heavily upon a very strong visual side with fancy cut scenes, beautiful and unique designs. I guess I can only speak for myself here, but one of the series' biggest draws has always been that with each installment, one was presented with a brand new set of characters, in a brand new world. That draw just seems to weaken a bit if the "brand new characters" and the "brand new world" look a bit too similar to what we got the last time around.
