The newest blogcast from Major Nelson, reviels that Epic fought for an Xbox 360 with 512MB memory. Microsoft first wanted an Xbox 360 with 256MB memory, Epic called Microsoft and showed them Gears of War with only 256MB memory.
Then Microsoft announced the final hardware, with 512MB memory. Epic then became the first developer that had to work with the final Xbox 360 hardware. Later that day, Microsoft's 'Chief Financial Officer' called Epic and said: "You guys just costed me $1 billion", and Epic's Mark Rein responded with: "No, we just did 1 billion gamers a favor".
