There is diffinitely a difference, although no much of one. =O
Ven has brighter hair, larger and lighter eyes, and lighter skin. -points out the obvious-
That's just the camera the guy used. I don't think the lighting really is that significant in reality.
Interviewer: What is the importance of story?
Nomura: For example, the name Xehanort is bought up in Kingdom Hearts 2. The game will answer several things like, "Why is the elderly person who appears in Birth by Sleep bringing up the same name?" and ,"Why is he wearing the same clothes as Ansem in the original Kingdom Hearts?" Another thing I want to bring up, is ,"Ven has the same hairstyle, face, clothes, and voice of Roxas, but just who is he?
Interviewer: Is the voice actor of Ven the same as Roxas?
Nomura: Yes, it is the same actor. Therefore the player will only look at Ven as Roxas from Kingdom Hearts 2.
However, are Roxas and Ven really the same character?
Moreover, what about the mystery surrounding the existence of Ven and Roxas?
These are keys that will be revealed from playing Birth By Sleep. You will be able to separate Ven from Roxas with ease; I will hint though by connecting the story between Roxas and Sora, you will understand who Ven is.
OF COURSE THERE IS MORE TO READ BUT THIS WAS THE ONLY PORTION THAT HAD TO DO WITH THIS TOPIC. LET ME KNOW WHAT YOUR THOUGHS ARE ON THIS.
People seem to have completely disregarded that post.
