I was wondering about that multiple personality disorder thing on Wikipedia, is the person who wrote it being serious somehow or is it total hogwash? It sources some Famitsu interviews, but the links don't take you anywhere as it's supposedly info from the physical magazine.
One thing I liked about the trailer is that despite looking like a brooding young man, the things Noctis says in the conversations that play over the gameplay segments make him sound like a brash shonen dude. Not sure how I'd feel for it to be the split personality trope, but Nomura did say we'd be surprised...However, not everything is right with Noctis. He begins to develop multiple personality disorder and feel the presence of another person inside him. This other person believes that there is nothing either morally good or bad and that fools have set the rules in Noctis' world. When this other person takes over, Noctis' body becomes far more powerful and his eyes turn crimson red. However, the personality of this other person is cruel and immoral. They are also very intelligent and cunning. Noctis does not know where this other person has come from, but he knows that they are far more powerful than he is. For Noctis, the battle becomes not only reclaiming the last crystal, but also reclaiming himself.
