According to the post, 2.6 million copies of Fable II have been sold so far. Those millions of gamers have unlocked over 66 million achievements so far. The easiest, unlocked 2.8 million times, was "The Whippersnapper," an achievement unlocked by collecting five gold pieces during the childhood phase of Fable II. That is more than the number of copies sold, which can be attributed to multiple gamertags per console and games being traded.
