My favourite characters are Vivi & Freya.

Good choices! Vivi's character and story is really lovely in particular. I think 9 has remained my favourite of the series for so long because it feels really quite fantastical. After slogging through FF8, which wasn't so bad really, it was nice to go back to something more "traditional" in terms of fantasy. Plus, airships. Plus, Quina. Plus, the soundtrack. Oh god, I need to go and play it again now.
