In pictures: GTA IV's Liberty City vs. Earth's New York City

There it was. A quiet, thoughtful moment, right in the midst of our rat-a-tat assault. There's not much room for unnecessary thought during a drive-by shooting -- aim and pull the trigger, aim and pull the trigger -- but this one provided an odd moment of stillness and clarity. As time slowed to a crawl and a prostitute's unlucky encounter with our front bumper became a slow-motion aerial ballet, we saw the world. Peering out the window at our decaying urban surroundings, we could think of only one question. "What would this be like ... in a game?"

Grand Theft Auto IV attempts to answer that question, reshaping New York City into the architecturally approximate, but satirically scathing Liberty City. Flickr user (and blogger) Matthew Johnston has created a photo set that compares the Big Apple to its rotten, in-game core, with various real and virtual landmarks placed side by side. We think you should check it out.
