How much memory did GoW use?
Does that mean you can essentally borrow games and keep them on your HDD?
No you need the disc to load the game up even after installing. Once that's done it then runs the game from your Hard Drive.
It's a pretty ingenious feature, TBH. After seeing how much better Fallout 3 runs I'm sorely tempted to upgrade to an Elite.
