Microsoft has filed a trademark for Avatar Motocross Madness with the USPTO. No additional information is available, but it sounds as though it’s Motocross Madness only with your XBL Avatar as the driver. We could be horribly, horribly wrong though. The last game to be released in the series was Motocross Madness 2 back in 2000. We’ll send a mail. Via: Eurogamer, Fusible.
