”According to O’Connor, the new features in Halo 3 are partly the result of something Bungie designers have long been doing: keeping up with fan feedback and tracking how gamers interact with the company’s products. In 2003, for instance, a series of Web-based videos titled Red vs. Blue, created by Rooster Teeth Productions, a production company in Austin, Tex., used graphics from the original version of the Halo game. The films’ popularity neatly coincided with the growth of video-sharing site YouTube, and each episode got hundreds of thousands of hits. Bungie took notice. Creating the videos, which fit into a genre called machinima, wasn’t particularly easy—and required additional, sophisticated equipment. So for Halo 3, Bungie has built a feature that allows players to create elaborate films from within the game itself. Because the games and films are rendered in 3D, players have full control of the camera, making it possible to move around a given scene’s action as it happens.
