Interesting article over at Escapist magazine regarding story telling in computer games, using Halo as the example. The basic premise is that games can only tell so much of the story. Books, comics etc provide the depth and breadth. Judging from some of the comments not everyone is happy with the resulting consistency in the Halo universe.
More significant in the article is how 343 Industries are not only providing a structured environment in which fans can explore the narrative universe but also giving them with a large network of opinions and perspectives on which to draw and form their own. It goes on to predict that 343's site will become the epicenter of Halo fandom.
In the past, game companies have mainly relied on fan sites to provide this. In the future, this may be different.
The Times They Are a-Changin.
