The OP is absolutely not talking about making Candy Crush. They ARE talking about making art. Both can exist in the same world and be successful. The existence of and success of reality TV doesn’t negate the art of filmmaking and the enjoyment of watching a movie. Same with games.

OP is invalidating the blog with the reasoning of detail, art, taste, etc is necessary for a good game.

I am saying that a small subset of people care about this given what people choose to play in practice. It's currently much, much easier to not care about these things and focus on the cognitive aspects to capture player attention, and the human cognitive incentives are not stacked in favor of OPs view.
