I don't want heroic badassed characters or effeminate cheery characters. I want to decide what personality my main character will take on. I want to make his decisions, not just see some actor play the part for me.
Final Fantasy is called an RPG, which is ironic since there's hardly any role-playing at all. Every now and then you're presented with choices, but they rarely affect your character's personality in any significant way. Ever played Knights of the Old Republic? Your main character is basically a blank slate, and it's up to you, the player, to build his personality based on your actions and conversation choices. That's role-playing. I want a Final Fantasy main character who is a blank slate.
I was always offended by FFX. They give you the option to rename the main character, so I took this opportunity to name him after myself. I was shocked when it turned out that 'Sean' would be an irritating wanker who rarely ever thinks before he opens his mouth. That's not the role I want to play at all. From now on, I just leave him at the default name.
