A few thoughts on the article, and also other things like the "low prices and sales destroy the value of games".
As was said somewhere, the only "problem" currently is that there are so many developers, ie. "too much" competition (especially on the indie market). That is basically which causes all the grazy sales, people not buying at full price or even not buying at all, most indie developers having hard time moving out of their parents' home on game sales alone etc. Tough. So many available choices for consumers.
The author practically said the same himself, when he said that if your indie game has ever been released for consoles, even if it failed here, it will get lots of recognition and free marketing on PC by that fact alone. Why? Because you've gone through some kind of more or less rigorous screening before you got your game published for consoles, ie. less competition (after the screening). The few lucky ones who make it to the consoles, get extra recognition right away.
I find it a bit hypocritical for some (indie) developers to complain that it is hard to get your title any recognition it the vast sea of PC indie titles, and at the same time concede how nifty it is that any one-man team can enter the PC gaming market with their indie title. You can't eat the cake and keep it too.
The author talked about how content is king, not gameplay. That is certainly an interesting question. If you have the muscles, it may be much more foolproof to make something with lots of content, and not trying to shine with trying something completely different with gameplay. I guess that's why we see so many "movie-like experience" games from the big studios, even if it restricts the gameplay in many cases.
It is partly the same question as the former GOG discussion, are you more interested in e.g. the story or gameplay/challange in your games. One old game that I personally found rich on both content and gameplay was Starcraft, and I liked it for both reasons. But if I had to choose between the two, I would have rather seen them drop most of the content (like story, music, FMV etc.) than gameplay (like having three completely different SC races to play; I consider that to be more about "gameplay" than "content"). I presume also that all the competitive SC players in Korea could have cared less about the story or the soundtrack.
It may not be easy to shine with gameplay alone these days, but when you do, you may really strike gold, like the Minecraft dude I guess (albeit I have no idea if Minecraft really made him a billionaire after all).
