Rage will span three discs on Xbox 360 and require an 8GB install on PS3, id Software creative director Tim Willits has confirmed. It was rumored that Rage would have a large install and multiple discs on 360, but it seemed as if id was leaning toward a slim-and-trim two-disc set, stating that a separate multiplayer disc-swap would be "fail." id didn't have to pick a disc number for the PS3 version of Rage, effectively utilizing the Blu-ray drive to hold all of the game's gigs, something that Willits seemed very pleased about:
"Sony was great," Willits said. "Kudos to Sony for letting us do that. They don't allow every game to do that. So definitely, hats off. 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."
For 360 versions, Willits said id recommends installing the game to the hard drive, or if you don't have the space for all 22GB, after installing and finishing the first half of the game from disc one, uninstall it, and then install disc two. There isn't a reason to disc-swap after completing the first half, and "you don't really need to install the multiplayer disc if you're really tight on hard disk space," Willits said
