Modern Warfare 2: Most Pirated Game of 2009
The good news: Modern Warfare 2 made more money than any game ever. The Bad news: It was equally popular with pirates.
"In just five days of sell through Call of Duty: Modern Warfare 2 has become the largest entertainment launch in history and a pop culture phenomenon," Activision CEO Bobby Kotick said commenting on the game’s success. This is, of course, reflected in the number of pirated copies being traded on BitTorrent.
