LOL. To be honest: I only watched one Shrek movie partially. I'm no fan or something like that. But different characters are necessary for a fun racer to work. And I don't know or like the characters of Crash Kart, Konami Kart or Cocoto Kart more. I wouldn't even know which environment would work best for a kart racer. There is Nintendo's Mushroom Kingdom, of course. And SEGA will ship a racer with different SEGA characters next year. But otherwise movies like Shrek or Madagascar are a good base for titles like fun racers.
