Different methods of talking, or additional words.

[MJN SEIFER]

I notice that a few Final Fantasys have at least one character who either speaks differently, or has a particular phrase that shows up in his or her sentance. For instance, in FFVI Cyan spoke in a ye olde type dialect and called everyone "Thou" in FFVIII there was Ultimecia with her strong accent (shown by replacing all hard "Cs" with a "K") Fujin would only shout one or two words at a time (this is not an inpediment, as she speaks normal in one scene) Rajin often added "Ya Know? after each sentance, and Wakka in FFX did a similar thing with "Ya!" Also I hear Reno in FFVII also had one but it was taken out, but he said "Zo" or something (anyone know what that means).

Is there a particluar reason Square does this but I wondered.
