It's ironic that GTA became a football in the debate over sex and violence in video games, because where it belongs is in the debate over whether video games count as art. No game developers are more radical and more passionate about the storytelling power of their medium than folks at Rockstar North, and GTA IV is the company's most ambitious work ever. It's the story of Niko Bellic, an Eastern European soldier-for-hire fighting his way up the organized crime ladder in an archly satirical version of New Yo I mean, Liberty City. It's a grade-A shoot-'em-up that doubles as an interactive novel and triples as a sly critique of American consumer culture.
