I like characters that are possitive in thinking but not overly hyper and they must have a dark part of their past that is mysterius that you gradualy find out over the course of the game.
Honestly I like depressing up beat and cocky characters. I don't like one more then the other really it just depends on how good the character fits into the story that makes him a good character or not......He can be really depressing but if you give him a good reason to be from his past that is revealed later in the game and him gradually coming to his senses and he fits the story then it's all good.
I hate over cocky characters like seifer who really are all show but no blow yuh know?
I don't relate to them and they annoy the heck out of me. But if they fit in the story well then they can be good as long as they mature a little dearing the game, but I prefer those characters as a party member or a bad guy but not usually as the main guy (or girl).
