On July 8th, GameMill announced that they are making another Nickelodeon Kart game. It is now available to preorder at major retailers for $49.99
Nickelodeon Kart Racers 3 will have 10 more characters at launch then Nickelodeon Kart Racers 2. All the characters will be fully voice acted. You can customize your pit crew to give you unique abilities. You can change your vehicle into a watercraft to navigate through water better.
I am very curious about Nickelodeon Kart Racers 3, especially if they have the original people who voiced the characters for the game. I might want to play this, I don't know yet.
