The Monkey Island game was heavily influenced by the Disney ride and (as sibling comment noted) Tim Powers' book On Stranger Tides. The Venn Diagram of who influenced who is nearly a circle, as the game was influenced by the Disney ride and the book and the movies were influenced by the ride and the games and the book and now the updates to the ride are influenced from the movies and the book. Disney even owns the Monkey Island games now in buying Lucasfilm, so all your pirate fictions are belong to Disney. (Yarr.)
