ModNation Racers brings Sony's creative karting to PSP, inspired by the LittleBigPlanet philosophy, in which you customize everything, from the driver to the kart to circuits you can design and share online. The snappy karting and the accessible yet deep creation tool make it a generous and original proposition. Loading times and an at-times frustrating handling next to the best karters temper the enthusiasm. For fans of arcade karting and games focused on community creation, it is a convivial and inventive success.
