Well, before I go any further, props should be given to Frictional Games and its Amnesia: The Dark Descent for finally breaking the one million sale mark. But company owner Thomas Grip says in a blog post:
Despite that huge number of sales, what I think is more interesting is how good the monthly sales still are. Not counting any discounts, the monthly full price sales lie at over 10 000 units. This means that less then every 5th minute someone in the world is buying a copy of Amnesia. This is totally insane to me. The figures themselves are far beyond any guesses we would have made two years ago. It is also insane, because this number is actually higher than it was around three months after initial launch. That a game can still be going this good two years after is truly remarkable. This success is due to many factors, some of which are the uniqueness of the game (horror games without combat do not really exist on PC), the large modding community (more on this later) and the steady flood of YouTube clips (which is in turn is fueled by the modding community output).
Grip ends his post by talking a bit about the follow-up to Amnesia, Amnesia: A Machine For Pigs, and a “new super secret project”. The only details that he reveals about the new project is that it’ll be a horror game and in a first-person view. All I can say is that the market can use all the quality horror games it can get its hands on. Check out the blog post here.
