any reasons why you didnt list cartoons from japan? or china for that matter? i think naruto and one piece would make a great cartoon based AA/AC game ^ they are the biggest thing in japan at the moment, so they have to be good... otherwise they wouldnt be the biggest
heck, you could throw in sword art online too (another massively popular book turned cartoon)
Samurai Pizza Cats. Just because I love the license and it would be perfect as an open-world game around a colorful city.
Spider-Man deserves a great game as well. I'm always amazed at how often they seem to completely mess that up considering all the potential there is to make it truly great (and how easy it is to get it 'right', but they always seem to go another way...).
I guess they just go far too lazy with it too often. "Oh, it's Spider-Man.... it will sell anyway".
