GamePro's got an interview with Makoto Chida, Project Manager on the upcoming Ju-on game. In it, there's all kinds of tidbits on Japanese versus American horror and gameplay control systems that induce anxiety. But the best bit is this part right here:
Makoto: We believe that the Wii is the most ideal console to experience horror games and started development of this title under that premise. If the Wii did not exist, I don't think that we would have ever developed this game.
So if you hate the game, you know who to blame: The Wii!
