Hey, I can understand something like that triggering one hell of an identity crisis, but it's hardly grounds for attempting (and failing, which is why he's pretty far behind in my list of cool FF villains, behind Kefka, Kuja, and Sin) to unleash a global Armageddon.
As to whether FFVI is THE best there is, best there was, best there ever will be... I can't really say. I rank it just as highly as I do FFX (why all the hate? so nomura watched one soft core porn too many while designing the characters, at least the story was great) and FFIX. I just can't bring myself to say it is superior, or inferior to those other FF legends. It would be like my choosing a favorite child.
I will say that man, I love Kefka. He's definitely the coolest FF villain. The opera theme can give me chills to this day, as can so many of the themes. The characters were great, so was the story, and the battle system. It's an all around awesome title.
I don't want to come off as a sakaguchi fanboy, So I will give my respects to FFVII. It's a great title, just not THAT great. and call me petty but I have issues with Nomura's bahamut designs. I mean what is up with his fascination with splicing the king of dragons with a chicken? But yah, FFVII is definitely one of the better of the later generation Final Fantasy titles.
