Ok, less sexy dresspheres. More covered up ones. The trainer, black mage, white mage, samurai and dark knight were the only ones that you could wear and not look like a prostitute.
But remember that the game was for the Rikku and Yuna fanboys, so less clothing the better. I agree though, more covered up dresspheres would be nice. And maybe some more playable new characters. I dont want to replay X2 with X's characters, but 4 would be nice instead of 3. Maybe a support guy character?
