GameDaily is hosting an article looking at the phenomenal popularity of Achivements on the Xbox 360. Even the marketing team that came up with the idea is floored by the incredible popularity of what CliffyB referred to as 'nerd cred'. From the article: "Achievement points are changing the way gamers play. While the tendency had been for people to play a game through to the end and then toss it into a closet, many gamers are now going back and playing them again, this time to unlock achievements to boost their Gamerscore. Or if they only played the single-player version, to go back and play the multiplayer or online component. Or to go out and buy games they would not ordinarily have purchased. Or to rent games."
