PS3 Owners are becoming very accustomed by now you would think to Hard Drive installs but usually these come in at around 3-5GB. Upcoming racing giant Gran Turismo 5 will be upstaging the rest of the PS3 library with an install coming in at 10GB.
Don’t freak out just yet though as this option is indeed optional. However should you choose to sit through the install, Kazunori Yamauchi has promised players will be treated to a smoother experience. I would hope with such a large install that the game would run with zero issues and we will see when the game releases November 2nd.
