I think the author is talking about the feeling of achievement. And that the only reason people care about (have the goal of) video games is that feeling. Basically, he seems to be arguing against wireheading, while those here arguing that all achievement is fake or that all achievement is real are effectively claiming wireheading, living in a permanent VR simulation, or similar is just as good as the real world.
