When the New Xbox Experience was released last year, one of the greatest features of the update was the ability to install games to your Xbox 360 hard drive to help decrease loading times. Sadly, not all games benefited from this.
Most older titles were designed to be played from the disc and developers optimized data on the discs, often duplicating it in various regions on the disc, to stream loads. Games like Halo 3 and Crackdown were actually slower when installed to the hard drive.
The Crackdown team though recently released an update for the game that will remedy the situation, making loading from the hard drive a more optimized experience. It's a good time to give the game another go to get yourself hyped for Crackdown 2.
