Harry Potter is a horrible example of "indie" publishing. Rowling's books were rammed through the largest publisher machines in the world and were cranked out completely corporatized.
A better example is the chick on Amazon who is/was the #1 ebook author as far as copies sold. She sells her stories for 1-5 dollars, and outsells most other ebook offerings combined. She isn't even that good. But she's cheap, and is totally "indie".
Which proves Cliffski's point wrong.
My problem with Indies charging 60 bucks for a game is that I frequently might only play said indie game for an hour or two before moving on to other stuff. His Gratuitous Space Battles for example *maybe* got 3 hours of life out of me. And I think I paid 20 bucks for it. Not the greatest return on my money investment.
