For companies like Valve and Stardock, selling a million is more than enough.
Say L4D sold 2 million copies on Steam at $50. That's $100,000,000 in Valve's pocket because (assuming for time's sake that we omit all the copies sold on that 1/2 off sale) Valve and Stardock are both self-publishing, and both own their own platforms, which leads to massive profit margins.
Something I'm sure EA and Activision are quite envious of.
