You know times have changed when the top three spots in Japan's software sales chart are no longer occupied by traditional fare, but rather a miasma of Mario mini-games, a balancercise board and a glorified automotive demo. Gamasutra runs down last week's top ten, highlighting Polyphony Digital's Gran Turismo 5 Prologue which made its debut in third position with approximately 116,000 units sold. Professor Layton bully, Wii Fit, found itself parking off in second position with 124,000 units after having switched places with Mario Party DS and its 180,000 attendees.
