So everybody keeps saying that Deadfire was a sales dud... got some hard data on that? And can anybody compare that with the original Pillars?
We have daily player numbers and data extrapolated from achievement numbers. And we try to be clever based on those.

But everything suggests it sold around 200-300K everything combined.
I'm not sure I've got the numbers right, but this is how I see this. Let's be generous and assume 280.000 copies with Steam, GOG and other sites.
At a price of $45, that's 45x280.000 = 12.600.000.
Steam's and other's site cut (30%) = 3.780.000
Taxes (I'm ont sure about american taxes, but maybe 10%?) = 1.260.000
That leaves us with 7.560.000. Game's budget could be around 10 million, of which 4 milion is crowdfunded. So Obsidians own contribution is 6 million, which at this point Obsidian has broken even, even if we take some more expenses into account (distribution costs and publisher PR). Which is a disappointment after PoE1, but it is not losing money at least.
