Uh, it occurs to me that not everyone pronounces the names in this game the same way.
For brevity's sake, I'll go with the following:
Zidane = "Zi-DON"
Cinna = "SIN-uh"
Vivi = "VEE-VEE"
Steiner = "STY-ner"
Kuja = "KOO-ja"
Brahne = "BRON"
Freya = "FRAY-uh"
Quina = "QUEEN-uh"
Amarant = "AM-uh-rent"
Eiko = "ACHE-ko"
If there are any questions/challenges/additions to these, I need to know now, for continuity's sake.
