Voilà ce que j'ai trouvé: ça m'a l'air assez complet au niveau des licences etc.....
-17 Supercross Tracks for both MX and ATV riding
-Career mode with 3 series (250 East, 250 West, 450 Championship)
-More than 80 licensed motocross companies in the game to ensure authenticity
-Over 40 professional riders licensed to race against
-New improved physics and control system including reinterpreting the fan favorite "pre-load" from classic MX vs ATV games
