At the recent QuakeCon event, John Carmack of id Software discussed upcoming games Quake IV and Rage as well as some interesting comparisons between Xbox360 and PS3 development and storage technology.

From 1UP.com:

"While discussing the difference between developing games for the PlayStation 3 and the Xbox 360, Carmack admitted that he wants hardcore id fans to help influence Microsoft's business practices. He also confirmed something that was hinted at in yesterday's news that Rage will be squeezed onto two DVDs: Microsoft charges developers more to publish games on multiple discs for their system. Carmack speculates quite logically that this is probably due to Microsoft not wanting to look bad next to the significant storage capabilities of the PS3's Blu-ray disc technology.

Don't think that Carmack's some Sony cheerleader, though. When reminiscing on Quake Wars' "depressing" development cycle and launch, Carmack notes that Sony demands that games coming out on their platform after they've already been released on other platforms must have significant bonus content. He also makes a big deal of the fact that while Rage will almost certainly look and run better on the PlayStation 3, he believes the 360 is the better hardware over all, because id is having to put double the work into the PS3 port.

Talking about his own gaming habits, Carmack reveals that he actually plays Nintendo's systems -- both the Wii and the DS -- more than anything else. This may come as something of a surprise from one of the top guys at a graphics-and-power-focused developer like id, but Carmack says he loves playing Mario games with his children. Sadly, though, we shouldn't expect to see id games showing up on the Wii any time soon. Carmack believes Nintendo's platforms work in favor of first-party development and leave third party developers struggling to sell units.
