For ages, Polyphony Digital has been promising a Gran Turismo 6 track editor that lets you build the race course of your dreams. Well, it's finally here... if not quite in the form you might have expected. Download the Track Path Editor app for Android and iOS and you can design circuits for the PlayStation 3 sim on your tablet. It's not so detailed that you'll recreate every nuance of your local raceway, but you can trace paths with your finger, choose themes and add scenery. Think of it as a way to extend the life of GT6 beyond the occasional new concept car -- you don't have to settle for driving on Autumn Ring or Brands Hatch for the hundredth time.
