Frictional Games was officially put on the map when the 11-person development team made the horror game Amnesia: The Dark Descent. Frictional Games co-founder Thomas Grip has revealed that the game cost $360,000 during three years of development and has now made back ten times that.

“As always, let’s start with the sales and some numbers. The first thing will be to figure out how many units we have sold in total, which is actually really hard to pin down. The biggest reasons for the uncertainty is that Amnesia was part of the Humble Indie Bundle (HIB) earlier this year and Potato Bundle last year. Both of these account for quite a lot of sales. Without counting the units bought there our total lands at 710,000 units,” wrote Grip. “Adding all HIB and Potato Sack sales gets us to 1,360,000 units in total, which can be called the optimistic figure. This means that, optimistically speaking, Amnesia has sold almost 1.4 million units! This reasoning is not strictly speaking invalid, but I think that one should not really count anyone that bought the bundle and already owned Amnesia as a proper unit. A slightly pessimistic guess (not far from reality I think) is that 2/3 of every bundle and pack buyer already owned Amnesia. This gives us about 920 000 units in total, pessimistically speaking. So saying that we have sold a million units seems fair. Wait… a million units! Oh s***!!”

“Despite that huge number of sales, what I think is more interesting is how good the monthly sales still are,” he continued. “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).”
