When gamers think about the Xbox, they often think about Halo and Gears of War. At one point, there was a third series that was pretty popular during the Xbox 360 era. This series was known as Crackdown, and it brought players to a sandbox playground where they had the freedom to do what they wanted. The game prided itself on the open-ended nature of its gameplay and was critically acclaimed for it. Crackdown would go on to sell millions of copies and kickstart a video game franchise that did not live up to the original title.
