The Grand Theft Auto series is the ultimate commentary on modern America. Greed, lust, money, and crime are wrapped together into a Las Vegas buffet of a game that is entertaining, insightful, and overwhelming in its sheer variety.
What fascinates me most is the way GTA represents the tempo of modern culture better than almost any other medium. Everything from the music playlists, the polygonal landscapes that mimic real cities, the caricatures of celebrities, and the fascinating antiheroes. Whether you take it as allegorical, symbolic, or literal, the Grand Theft Auto series is the modern epic.
GTA IV still remains my favorite because of the story and Niko, who is my favorite character in the whole canon. He embodies and represents the American dream, twisted underbelly and all.
