Not in my opinion. I don't consider any game backed by a large publisher to be indie. For me, indie games are games developed by independent studios without the backing of huge publishers.

Edit: When I say backed, I mean being financially supported by a publisher. Heavy Rain was backed by Sony.

Retail stores are partly at fault.
Over the years before Steam came along they constantly reduced the amount of shelf space dedicated to PC games, it actually reached a stupid state, piracy began to run rampant.
Then Steam came along and solved all of the PC gamers problems.

Besides, Brick and Mortar stores may have stopped supporting PC games, but dozens of online business's have sprung up dedicated to that target demographic, like Green Man Gaming, Gamers Gate, Good Old Games and the plethera of CD Key websites.
It's Capitalism at it's finest, if there is demand, then that demand will be met by new business's, if you neglect the demand and don't change with the market conditions and fail, then you deserve to fail, that shouldn't be something that's prevented by government bailouts or special market conditions.

Besides, the "digital" price matching is pretty laughable, you looked at a new released game on the Xbox Live Network? It's usually the same price or more expensive than the version you can find in store, digital should be cheaper by default, there is no packaging, shipping, manufacturing or other extra's like manuals, guides and such that you're getting.

As for the last line on your post, it's difficult to understand it, could you elaborate? From what I can understand you're basically saying that AAA games don't benefit which is ironic, because even AAA games on Steam have benefitted from the sales, hence why Valve is happy to discount it's own franchises which have sold millions of copies already.

Considering Heavy Rain was supposedly to be exclusive to the Xbox 360, I can say Sony did not financially supported the dev, except for the publishing cost.

They funded the game development and they took most of the money(surely developers have some percentage) from the game sales until the game returns the funded money. Later the percentage of the profit for the developer increased and they are getting big royalties.

Wait, are you telling me that Sony did not pay for any of the marketing costs or the development costs of Heavy Rain? Here's an article which led me to believe that Sony did indeed back the project specifically the final paragraph:

You are not. But again, you are not an AAA or AA developer, you're something in the middle!!!

I cant say what I want to say, so I'll just say "sure"

I'll quote something interesting from that source:

"David Cage, says that the only reason it was able to become a "commercial success" was because Sony had enough "balls" to take a risk on the Quantic Dreams developed product".

Look at this:

"David Cage, says that the only reason it was able to become a "commercial success" was because Sony had enough "balls" to take a risk on the Quantic Dreams developed product".

Hence why they had already the game finished. That's why he's praising Sony; because he asked Microsoft to publish his finished game and they rejected it. Sony only paid for the publishing costs.
