Rob most of the shows you and others mentioned were at their height in popularity before the NES was released or really got rolling. I agree with BoJay, the games would likely have stunk. Almost all of the big licensed games were horrible, because they went to companies like LJN, Acclaim, Activision, or Data East, which produced bad games most of the time. What really made no sense were the licenses used on stuff like Felix the Cat.
I think the main mistake they kept making was trying to shoe horn a feature film into a game. They should have instead taken the characters and guided them through a new, original adventure. Which is usually what happens nowadays.
