I used to think about video games, "This is clearly an amazing, new narrative medium, and it's going to be mind-blowing when people get to grips with what's possible within this medium." It took us a century to get really good at film. Video games are at a much earlier stage.
The key relationship for writers in film is producers, because those are the first two people involved and the ones who work on it intensely in a private way without the big machinery of film.
