One of the reasons I play this game over and over is because there isn't any decision making you have to do to develop your characters. Your biggest decision is pretty much whether to give Rydia a bow or a rod.
Or a whip, friend. Or a whip.
Never forget that if you give her a whip, imagine her clothes to be all black, and then change her class to Dominatrix... Well, maybe then we can get her an encore appearance in Final Fantasy 30.
