PC survival horror Amnesia: The Dark Descent has been purchased 200,000 times in the four months since launch - well above its creators' initial estimates.
A post on Frictional Games' blog read, "Summarising all sales since release actually puts us in a state that we never imagined being in.
"When counting all online sales as well as the Russian retail copies, we have now sold almost 200,000 units! This is a tremendous amount and more than we ever thought we would. Our 'dream estimates' before release was something around 100k, and to be able to double that feels insane.
"Note that more than half of these units have been sold at a discounted price (with as much has 75% of the price off)," the post continues, "so the total earnings are not as much as it first sounds. Still, we are in incredible good financial situation right now.
"Also, the daily sales are still quite high and the average has not dropped below 200 units yet. This means that we can still pay all daily costs from these sales alone, allowing us to invest the other earnings into the future"
The game deserved every sale. The tense indie horror won a frightfully impressive 8/10 from Eurogamer's Quintin Smith back in September and was voted the 38th best game of the year in our annual reader's poll.
The developer believes the success of the game is a sign that PC gaming is in fine health and proof that exclusives are viable on the platform.
"With these figures at hand, we must confess that it gives us new confidence for the PC. The sales that we have had (and are having) are more than enough to motivate developing a game with the PC as the main (and even only) platform.
"Based on what we have seen, the online PC market is just getting bigger and bigger, and we are convinced we are far from the end of this growth. We think that other developers that consider making their game exclusive to a console might want to think again."
