In addition to confirming that Ridge Racers will be a launch game for the December 12th unveiling of the PSP in Japan, Namco has put up three video clips showing their upcoming PSP game, Ridge Racers, in action.
All three clips run roughly 2 minutes in length and require Windows Media Player to view.
Be aware, the web site hosting these clips is in Japan. (You're not going there for the text anyway, are ya?)
