While the storytelling in games is getting so much better, you look at something like Grand Theft Auto V, which I thought was really beautifully written, it doesn't really need a movie because it is a movie. So I think you need a unique game - you either need an incredibly talented writer and director to come in and put together an amazing vision, or you need a game like Metal Gear, which is very cinematic, has a huge amount of history behind it, but whose cinematic experience is very different from what you'd get in a theater.
