If there is any game in the history of gaming that you know for an absolute fact would end up making a good movie that could end up as a family classic that game would definitely be any one of the Monkey Island games. The LucasArts and later Telltale Games-run franchise of point and click adventures remains one of the most beloved series, combining action and humor in a way that feels like a good Pixar flick. You could argue that they already are more interactive movies than games.
But we will never, ever see a Monkey Island film, and it's all because of Disney.
I'm not just talking about the fact that Disney bought the rights to all LucasArts titles last year, though that is certainly a part of it. The future of several series and franchises remains up in the air. Telltale games haven't made any new additions to their incredible modern entries into Lucas Arts titles like Sam and Max since the Disney acquisition, nor have any been announced.
