My entire argument stems from the idea that you can ascertain quality from these ratings, which I am refuting. The rating is "correct" in that it is measuring something, and as long as people keep in mind what that something is, there is no problem. But this article, for example, uses the flood of positive reviews to make the case that it is one of the best of the year, which I believe is faulty reasoning.

What I meant by certain is that the reviews are more clumped together (again if you had a score - even though it isn't present presumably you could attach one to these reviews), so there's more agreement among different people about the quality of the product. If you don't agree that games can be more or less polarizing, you won't agree with this point unless I can back it up with data which I'm not going to spend time doing. You could go through Rotten Tomatoes and compare Critic Score with RT Score because they surface both those values and see how closely they track on different parts of the spectrum.
