Well, it appears all our raving about PC horror game Amnesia: The Dark Descent paid off some -- developer Frictional Games reports sales have exceeded expectations. As an independent developer, you typically live from game to game with not much in the way of security -- thankfully their 24,000 sale requirement was met and then some: Amnesia has broken 36,000 units.
This may not be much compared to your million-plus selling mainstream console titles, but remember also those cost much, much more to produce and promote (many millions, sometimes hundreds of millions). Counting the pre-order discount, we can conclude Amnesia has pulled in roughly $600,000 in revenue. Frictional notes this means they've recouped all of their production costs and then some.
Naturally, they long for better days still, where they can live on comfortable wages, and it may happen soon enough yet. In any case, they're planning their next title already, and are pleased to report they can take their time with it as they know they can finance it themselves, unlike all previous titles which they were forced to rush. Whatever it turns out to be, we already can't wait to play it.
