The big disagreement I have with your argument is this: sure, games for the most part get reviewed -- the same is true of literature. There is criticism, as opposed to review, of both games and books, but most readers, like most gamers, are interested in consumption first, and, if any external analysis at all, consumption-focussed reviews more than explanatory criticism.

For either medium, the community engaged in critical review (largely academic) is not actively followed by either most consumers or most producers of the works in question -- there's some feedback (in both literature and games), because some consumers and some producers in each medium also engage in, or at least follow, criticism and let it influence how they consume or create works.
