Pushsquare.com has posted news of GT5 producer Kazunori Yamauchi discussing GT5's 'Course Maker' feature. He stresses that its not a full track editor but will allow the user to select themes for the track i.e location types, the number of sections, length, weather and time of day and then allow the user to edit each section and also edit the corners to define the width of track, how tight the corner is and banking.
