id Software creative director Tim Willits revealed that the PC version of Rage will require 25GB of hard disk space for installation, the PlayStation 3 version will fit on a single Blu-ray but will require an 8GB installation on the console's hard drive and the Xbox 360 version will come on three DVDs with an installation option that eats as much as 22GB of the console's hard disk.
"Sony was great. Kudos to Sony for letting us do that. They don't allow every game to do that. So definitely, hats off," Willits said about Rage's PS3 installation requirement. "What we were able to do is install all the textures to the highest level. What is nice about the PS3 platform is that it's just one platform. Everyone has one Blu-ray drive, one hard drive, it's all the same. Some of the other systems you have... should I install it on my 360? Should I not install it? So yes, it's very nice."
As for the Xbox 360, hard disk installation isn't mandatory and the user can install one disc at a time to save time and hard disk space.
"We recommend installing the game to the hard drive, but you don't need to install all three discs," Willits explained. "If you don't have the space available on your hard drive, don't stress. Install the first disc, the first chapter, the first half of the game, then when you're done, uninstall and install disc two."
