With RAGE being touted as one of the games to deliver on the visual front, it's no surprise that it'll take a massive portion from the PlayStation 3's hard drive.
It has been confirmed that the shooter, currently in development from id Software, will require a whooping 8GB installation size on Sony's console. Oh, and it's mandatory.
The Xbox 360 version of the game, meanwhile, doesn't require a mandatory installation but you can install the game onto the console's hard drive for 22GB.
Thanks, GameRadar.
