I hope it sells well, and brings in more people to the series. It's just that a game like Final Fantasy relies heavily on it's characters and then story. If I don't like the characters, I'll never be able to enjoy the story and therefore game. It's unfortunate but that's just how my tastes seem to work. As it's a demo I can forgive some of it's issues but I can't really see them changing the characters too much now. It seems as though they have been fleshed out and are at their final form or close to it. They've already confirmed that they are the four playable characters too, I'm sure.
