Tim Willits, creative director of id Software, said in an interview (with Digital Foundry) that the PlayStation 3 version of its upcoming game Rage will require an 8 gigabyte game install, and the Xbox 360 version will utilize three discs.

Willits praised the hardware for PlayStation 3, saying, "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."

He also announced the versatility Rage will have with the three discs for the Xbox 360 version. "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."

Rage is scheduled for release on Oct. 4 for the PlayStation 3, Xbox 360, and PC.

That's a pretty hefty install for the PS3 version, but the game does look pretty damn sweet. Also, it's 3 discs for the 360? I wonder if you need to do any disc swapping to access previous content...
