"Let's agree to this one point right up front, whoever came up with the idea of Achievements is an evil genius. Those ultimately meaningless points and their culmination in the Gamerscore have led to a revolution in the way we play games. Gamers who would normally blow through a shooter in five hours or casually jump online to play a quick match with friends are now pouring hours and hours into games just so they can see "Achievement Unlocked" keep popping up until they claim all 1000 points. Not only has this now-established phenomenon changed how we play, it's also fundamentally altered what we buy. Achievements are Microsoft's secret weapon in the console war, and they are why the Xbox 360 will end up winning the day."
