Amnesia: The Dark Descent becomes a million seller

When is a game too successful to be considered indie? Frictional Games' indie horror game, Amnesia: The Dark Descent has become a million seller.

Oddly, figuring out the exact sales numbers actually takes some work due to the game's inclusion in the Humble Indie Bundle and Potato Sack. Without accounting for these bundles, the game has managed to sell over 700K units. Admitting that a number of bundle purchasers likely own Amnesia already, Frictional's Thomas Grip calculates that the game could have sold almost 1.4 million units.

"The figures themselves are far beyond any guesses we would have made two years ago," Grip explains in a blog post (via Joystiq). "It is also insane, because this number is actually higher than it was around three months after initial launch." Certainly, word of mouth has helped propel the game's status and sales well after its initial release.

Reaching a million sales is an accomplishment for any game, let alone a game that cost only $360,000 to make. "It has since earned more than ten times that. Take that investors we talked to in 2009!"
