Kenny Kramer writes: "For years the little plumber from Nintendo has been the face of video game kart racing, and rightfully so as no one has come close to toppling him from the top. Sony is now making another run at champion of karting - Mario Kart, but has wisely broken away from the typical mold with Modnation Racers for the PSP. Modnation Racers takes a little bit of everything Sony and adds it all to the kart racing genre. If you haven’t been following the title, think of it as LittleBigPlanet meets Mario Kart. The racing almost takes a backseat to the “modding” of your vehicle and ride."
