Speaking at Quakecon, John Carmack shared a few details about id's impressive upcoming shooter Rage -- and it's bad news for those 360 owners who are still struggling on with the first generation 20GB hard drives, and possibly even those with larger drives who have downloaded a lot of content.

Those who choose to install Rage for Xbox 360 will have to set aside between 21 and 22 gigabytes of space for the game's content. The game, set to arrive on two DVDs on Xbox, doesn't have a partial install option. Carmack noted that installing the game is "the way to go," presumably implying that running the game from the DVD will result in significantly slower loading times.

"On the 360 we don't have a partial install option; it's all or nothing, which is kind of unfortunate," said Carmack. "It means you have to install 21/22GB of stuff which takes a long time, but if you've got it and you play it on the 360 that's the way to go."

Rage hits PC, PS3 and 360 on October 4.

Thanks, VG247.
