Rely on Horror: "To date, Amnesia: The Dark Descent has sold over 200 000 copies in the four months that it has been available. This is more than developer Frictional Games ever thought was possible, in fact. From a post on their blog, Frictional stated they estimated that they might rake in 100k sales, but doubling that figure feels good. Real good. When you consider that most of the copies sold were discounted (with some as much as 75%) off, that’s no easy feat."
