Tom Bissell was an acclaimed, prize-winning young writer. Then he started playing the video game Grand Theft Auto. For three years he has been cocaine addicted, sleep deprived and barely able to write a word. “There are times when I think GTA IV is the most colossal creative achievement of the last 25 years, times when I think of it as an unsurpassable example of what games can do, and times when I think of it as misguided and a failure. No matter what I think about GTA IV, or however I am currently regarding it, my throat gets a little drier, my head a little heavier, and I know I am also thinking about cocaine.”
