the usual places are filled with gibberish, I think they've moved stuff about. Some Bspec stuff is mixed in with the Sierra stuff, probably for the cars that are lapping the track? pitstops, warnings for engine, suspension damage, etc
Sierra is like those other tracks, wide open environment, course maker themes confirmed.
Found car list, none hidden. Everything else has been nuked, even all the car, game options/mode descriptions, I wonder if the hybrid editor will still work? First strike to kill the save data hack?
Treasure hunting is dead and buried.
