One thing we can all decide on, is that they're fond of having at least one experienced figure, who's sort of been through the hardships and all that jazz. They've featured in every FF I've played except for VIII. I'm talking about guys like: Barret, Cid, Bach, Auron, Cid (IV), Tellah, and I'm sure there's many others, but I think Square know that they can't ever create a game with a bunch of mindless youths. They need a authoritative figure, who has seen it all.
