Interesting article about the thread title. I feel the final paragraph is significant:
"In games, perhaps the scarcity is players' time. And if that's right, perhaps an indie dev's real battle is to prove their game is worth time, rather than simply money. Thinking about it this way might help to pull indie games out of a current market price which is unsustainably low for the numbers many sell. And that really does matter to us all. If creative developers can't make a living, that's not only bad for them, it's also bad for us. We lose an important layer of experimentation, and PC gaming as a whole suffers."
