You know, I've been playing FFIV again, and I think it is a shame that none of the Kingdom Hearts games that feature Final Fantasy characters include characters from past games (aside from Setzer, whom only appears in Data Twilight Town in KHII). Including both Cecil and Golbez (from the time that he was awakened) would be a good way to show the two sides to every coin paradigm that is the Light and Dark. Cecil being a Paladin of Light, Golbez being a Black Mage of the Darkness.
