Liam Lambert, GIZORAMA - "Videogames are not movies. They share common elements and both present audio visual narratives, but that's about where the similarities end. I've made my feelings about videogame movie adaptations known before, mostly in response to possible Mass Effect and Deus Ex: Human Revolution movies. Long story short: it would be impossible to condense the amount of player choice found in those games into a single, linear narrative. So many players experience those games differently, and a movie that only picks one of many conceivable paths would just aggravate the very people it's marketed at. I did, however, express a more positive attitude towards cinematic adaptations of more linear games like Halo or Call of Duty.
Take Halo for example; it has a rich universe and back-story to pillage from without treading on the toes of any future Halo games, and its gameplay is linear enough for most players to have experienced it in roughly the same manner. Of course, there would be no "Legendary" mode for the movie wherein the main character dies and re-spawns 200 times before the film's climax, but for the most part, a cinematic adaptation of the Halo universe can, and arguably has been, done."
