I wouldn't say Mario is different from the Disney movies either.
Furthemore, Disney Cartoons are considered classics. Which, Micky Mouse is practically the prototypical Mario. Right up to where the latest Micky Mouse game essentially tried to copy Mario back.
Which Mickey Mouse classic would you be thinking of? I ask because the only one I know is Fantasia 2000, and that's nothing like Mario, and conveys a whole other level of emotion.
