i would change a few things in the story line basically love triangle stuff cuz i like to sit back and watch drama like in FFVII when you can choose who you go on a date with if you do everything right but anyway

i would put something like that in there and i would make wakka have a thing for rikku for awhile, auron have a thing for lulu one of the luca goers have a thing for yuna then tidus whoops their ass and tidus have a thing for rikku before sin takes him the second time
