Via Cathode Tan (who has some commentary of his own on the subject), a Guardian article attempting to ascertain who is at fault for crappy game movies. From the article: "Because, unlike cinema, computer gaming is a medium which requires the player to make things up for themselves. An individual game may be laden with 'plot points' but its narrative is always up for grabs. It is a format of scenarios rather than stories, elements which can be bolted together in differing orders with varying outcomes. Cinema, on the other hand, is designed for people who like to watch and listen, and who expect the film-maker to get their story straight before the movie reaches the theatres. Viewing a film based on a computer game is like hanging around in an amusement arcade, peering over the shoulders of other people playing video games. It has less to do with story-telling than conceptual shelf-stacking. And it is symptomatic of the painful death of the art of narrative cinema."
