Here's some shocking news just breaking from the Quakecon Keynote: Rage and Doom 4 will not be sold online via digital distribution. Rage, being published by EA, would be an obvious choice for EA's Downloader service, but apparently that won't be the case. The only way to buy the two games whenever they come out is in stores with boxed copies.
Additionally, Rage will most likely ship on multiple game discs for the Xbox 360. The DVD-only format for the Xbox 360 is its biggest limiting factor, since the Xbox 360-formatted discs actually hold 1GB less than standard 4.7GB DVDs (multiplied by two when dual-layered). And since the royalty charge per disc is actually surprisingly high, id hopes that Microsoft will make a concession for Rage, or else the company may actually have to sacrifice texture and asset quality to get the game to fit on fewer than THREE discs. The cost of the 3rd DVD alone would cost millions of dollars with the current royalty rate, says John Carmack.
When comparing the Xbox 360 to the PS3, the more spacious Blu-ray format is the only thing Carmack likes more about Sony's console. Everything else is better on the 360, he says.
