I don't like playing the nationality card when it comes to cars in the GT series. The way I see it- nobody complains about mostly British bias with Codemasters racing games, and I don't hear people complaining about mostly American bias with the Forza series, so why Gran Turismo and why Japan? I don't necessarily get sick of Japanese cars. I am never going to say something like "I wish Gran Turismo was less Japanese." In fact, I love Japan. I'd even want to see more American cars and a better emphasis on Australian cars (and maybe more Korean cars as well). However, I am not sick of Japanese cars at all. So my answer is No.
