Triverse writes, "Ever since Nintendo released Super Mario Kart on the Super Nintendo, oh so many years ago, companies have tried to copy that specific formula for success with varying results. Sega is one such company that has tried to take their existing stable of characters and create kart racing games with them as the stars (Sonic R on Saturn and more recently two of the games on this list). Even Sony got in on the action with Crash Team Racing on the original Playstation, even the WWE has a kart racing game out (on Playstation 2). This is one of those genres that is pretty much dominated by one or two companies (Nintendo usually doesn’t have all that much to worry about). We feel that the key to success in this genre is the characters, hence this list."
