Crash Tag Team Racing is a racing video game published by Sierra Entertainment and developed by Radical Entertainment for the PlayStation 2, Nintendo GameCube, Xbox, and PlayStation Portable. A Nintendo DS version, which was to be developed by Sensory Sweep Studios rather than Radical Entertainment was also to be released, but was eventually canceled. The reason for this is unknown. The game was released in North America on October 19, 2005, in Europe on November 4, 2005, and in Japan on December 1, 2005. [source:wikipedia]
