What I have always wanted to see in an FF game is a cast of characters where at least the main character or the whole main cast isn't composed of all teenagers or kids. Also, more non human main characters. I don't know about FF7, 8 or 9, and excluding online titles, I think the only games with non-human main characters or main cast characters were FF10 with that blue guy, and FF12 with Fran. I want more diverse, creative parties.
