As you probably know by now, Lionhead Studios is developing Fable Anniversary and they are accepting fan submissions for the in-game achievements with one lucky winner seeing their suggestion make it into the final game. Should you want to try your luck and have an achievement dreamt up by you in the game, all you to do is go to the Lionhead forum and let them know precisely what your idea is.
Eventually the (inevitably) large numbers of suggestions will be whittled down to just five by Lionhead with a public vote following soon after. Once the voting has finished the winning achievement will make it into the final game with the creator appearing in the credits and also getting a free copy of the game. All of the five finalists that reach the voting stage get a game t-shirt and a set of E3 badges.
Not a bad prize at all is it? Good luck and if you have any cool ideas for an achievement then please let us know in the comments below (after submitting to the competition first so no-one steals your idea!).
