During Tokyo Game Show last week we crashed Polyphony Digital's studio and chatted up Kazunori Yamauchi about ... Gran Turismo 6? Wait -- what? Just watch the interview.Selected excerpts below:Joystiq: Are there any plans to bring Gran Turismo PSP's "Party Mode" to GT5?Yamauchi: I'm glad you noticed that. What we really worked hard to make the PSP portable fun and interesting is in those types of details. Obviously, these are ideas we worked hard on and they will be carried over in some form into GT5.In Gran Turismo, with its ten years of history, the people that who good at playing the game are really, really good at playing the game. Of course, there are a lot of first-time players that want to get into the game, and it was a major theme for us to develop the game so it would be easier for them to get into it. With the party races and these game modes we've developed for the PSP, we've come to one solution for that aspect.
