Beyond that, there are several games in the casual space that are prime material for children’s television / movie. Mystery Case Files, Hidden Expedition (children’s Indiana Jones), and Diner Dash are just a few examples.

All that being said, it is certainly true that for most games, there is limited time spent developing a compelling storyline. I think most developers aren’t looking to create a game franchise they can build on over the next decade. They are looking to create a game with fun game play mechanics that will sell well quickly.
