Are there AAA game devs with 300 person teams who really think they can win without thorough documentation? WTF? "Release early, release often" is for webapps and small teams. When you're dealing with a AAA game there is such a huge network effect it's actually crucial to make the first release a good release. You then get all the word-of-mouth which drives the game industry. Most AAA titles that ship with bugs pay for it dearly in sales because gamers talk to each other and word gets out in a few days about just how finished the game is. "Release early, release often" can't possibly apply to AAA games with 300 person teams and fixed launch dates.
