I really -really- disliked this game. So much so that I will simply give my opinions on the characters and nothing more. They don't really deserve to be rated.
Eh. I'm indifferent to Edea. She was kind of the one who had to explain every detail to Squall. I would hate to be her. Plus she married Cid. But don't worry, because Edea was the nanny type who looked after everyone at this magical orphanage. It's nice in games where there's a surprise that one character is connected to another, like in Final Fantasy VI when you find out Shadow is Relm's father. But -all- of the characters having a connection? That's just not believable or entertaining.
