I hadn't ever really perused SteamSpy before but just browing around I gotta say goddamn that Sean Murray guy walked away with like 30 million dollars in the last 2 weeks just from No Mans Sky Steam sales alone. And that's after Valve took their 30% cut.
Well, there's region-specific pricing to consider as the game isn't USD$60 everywhere. However, even assuming for the moment that everybody bought the game from the Chinese store (which isn't even remotely the case, in no small part because it's a gift/trade-restricted region), ~750k copies sold is still ~$12.5m after Valve's cut.
