Lionhead Studios has already compiled their list of Achievements for Fable Anniversary, but they've saved one just for Fable fans to suggest their own ideas for an Achievement.
Have an idea for such an Achievement? Submit your best idea to Lionhead via their forums, and then the studio will pick their favorite five suggestions for the mass populace to vote on. You can even make a suggestion for the logo of the Achievement.
The winner will have their Achievement in the game, their name listed in the credits, and free copy of Fable Anniversary. The five finalists will all receive a Fable Anniversary T-shirt and E3 pins.
Think you have what it takes to truly come up with a fun and interesting Achievement? Now is your chance.
