From Wikipedia: Monster 4x4 World Circuit is a racing game published by Ubisoft, centering around Monster trucks. It was released on March 23, 2006 on Xbox (North America only), and later on Wii as a launch title for the system (November 19, 2006, in America, December 7, 2006, in Austrilla, December 8, 2006, in Europe and December 21, 2006 in Japan). It is similar to San Francisco Rush, with huge jumps and vast speed. The game is a sequel to Monster 4x4: Masters of Metal, although it lacks the Monster Jam license. A sequel developed by Ubisoft Reflections, entitled Monster 4x4: Stunt Racer, was released for the Wii in 2009.
