My take on it is that since the barriers moved, and because of where they moved the consumer experience is worse. And because the vetting takes place later, the developer's experience is worse.So, essentially, you're saying that those that should fail along the way get to hit market and wonder why they're not making revenue?
Or is your point rather that all of the shovel ware makes it actually harder for quality games to turn up a penny?
Before the barriers were at the cost of manufacturing and distribution. You could build a game on your own but achieving wide release meant you had to convince those with money or with power.
Now the barriers are moved all the way out to the end retailer. While it is good for the individual developers since they can get their goods more cheaply to market, it is horrible for the consumer. Where once the consumer had a small number of choices that had all been vetted and pruned to the high quality items, there is now an enormous pile of merchandise. Since no vetting has occurred the individual is left with the curse of too many choices. There is an enormous collection of choices, so many that they cannot sufficiently evaluate them to make a decision. A person who simply says "I want a game" can go to the marketplace, but there are over one thousand games added every day. There are many hundred thousand games already out there.
Since there is no way for the individual to evaluate the enormous piles of options themselves, the consumers turn right back to other sources of vetting. Instead of a financial barrier doing the vetting, they rely on the top-100 lists or the editor choice lists or whatever other vetting services to do the job.
So then the individual developers are kept in an even worse spot than before. Before they were usually stopped for vetting early, before they invested time and effort and money into the product. Now they are stopped for vetting late, after the enormous investments. Thus the marketplace is dysfunctional for the small developer as the market is more like a lottery for those who cannot afford the vetting process. And the market is dysfunctional for the consumer because they are faced with an overwhelming number of choices with no viable method to sort between the excellent products and the terrible ones, which are all presented with an icon, some screen shots, and a 99 cent cost.
