Actually, Alan Wake did sell well. It would have sold more, but was one of the most pirated games in history. Over 1 million units were pirated. So in a sense is a successful game and in my opinion was and still is (if you don;t count the pc release) the 360's best exclusive.
My ignore list is exclusive to trolls only. I should warn you though, it's crowded and the trolls imprisoned within are mean, anti-social and well... ignored.
