GT5 Interview - Weather changes in realtime while racing; Driver's management is extremely important in this game; Endurance races also have this weather feature; A-Spec & B-Spec are both equivalent in this game but they're included separately in the game

另外关于赛道编辑器
"Rather than being a fully featured editor – a feature that, Yamauchi confessed, was tinkered with but deemed too complex – the course maker allows players to select certain set parameters to create a track. A theme can be selected, with the Belgian High Fens or Toscana two examples, and the individual track sectors are then defined.

Sectors are edited individually, with frequency of curves, sharpness of corners, degree of topography and banking angle are set with a series of sliders."
