It is clear by now that violence in video games is thought more pernicious than comparable violence in more traditional media. Just look at coverage of Halo, the top-selling science-fiction series that is akin to “Star Wars” in its level of made-up mayhem. In the mainstream media Halo is often described as a “violent space epic” or a “violent shoot-’em-up game.” But when was the last time “Star Wars” was described as George Lucas’s “violent space movie”? For that matter, when was the last time anyone referred to “The Sopranos” as a “shoot-’em-up television show,” which at some level it was?
