This is a nice little video which should get you in the mood for the upcoming Gran Turismo Sport. In it, series creator Kazunori Yamauchi and Sony Worldwide Studios executive Shuhei Yoshida look back at 20 years of racing game development – and include anecdotes about their ambitions for the original GT right the way through to the latest version for the PlayStation 4. Remember to turn on captions, because a lot of the video is in Japanese.
