Or something akin to YouTube. In fact now that I think about it it would be very easy for Netflix to provide an equivalent of YouTube for user generated content where the creators get paid from the subscription revenue based on how much their content is viewed. Since there will be no ads, it can certainly become very popular.

In the game space, I don't think they'll be creating proper console/PC games, rather interactive movies as they have a few already on their platform. Not sure how popular they are though since I've yet to try any of them.
