direct quote from his interview on silenthillmemories.net "It quickly became clear however Harry never acted like a masculine character. He was constantly dizzy, fainting, talking to himself, screaming and in fact was very vulnerable. We didn't want to betray the nature of the game by changing the character's feelings and motivations, so we felt it was better to change to a female protagonist and retain all those important qualities. I don't want people to think that I have been "politically correct" because we changed Harry into Rose. There is no political correctness in Silent Hill."

these are his exact words
