Two things:
One: you're changing the premise. Earlier, we were talking about the game's "quality". Now you're talking about the game being "something the market truly needs". Those aren't the same thing at all.
Two: "if you build a better mousetrap, the world will beat a path to your door" is an unconvincing assertion. Distribution certainly does matter - it is literally impossible to succeed if people cannot get their hands on your product. As for marketing - word of mouth works sometimes, sure. But you effectively assert that word of mouth alone will guarantee success, and I just don't buy it. Especially in a market so utterly dominated by one or two really major players. I think you're being rather unfair to good products that don't have marketing budgets here - "Well, obvioiusly, you weren't really so good, because if you were you'd not need any advertising to ever succeed."
This is not to say that sometimes a given author might blame lack of marketing or distribution when the root problem really is that their game stinks. But just because some folks lay that blame falsely, doesn't mean all such complaints are unfounded.
