Aeris/Aerith

[Rase]

And I also call bull when you say a "limited" number of FFVII has her name as Aeris, while the rest has "Aerith". I've owned and played about a total of 20 copies, and they all say "Aeris." I need some proof.

I think you misread Ryu's statement.

Let's take a look at the Aeris V Aerith in English, shall we?
Aeris- FF7e, FFTe
Aerith- FF7e (limited number), FF7AC, FF7DoC, FF7CC, KH, KH2, The Japanese version of every single one of those games, The creator's own concept art.

He was saying that a limited number of English FFVII games have her name as Aerith.

I'll put this in caps.

WE ARE NOT TALKING ABOUT OTHER GAMES. WE ARE TALKING ABOUT FINAL FANTASY VII RELEASED IN THE UNITED STATES FOR THE SONY PLAYSTATION. OKAY?

Last I checked this discussion was first about why the character was sometimes called Aerith, then turned into whether Aerith or Aeris was correct. As far as I can tell pretty much everyone is still talking about the character as a whole here, not her appearance in a specific game. Well, pretty much everyone except you.
