As you may already know, I only put so much stock in a one-dimentional rating. Sure, it might give you a general idea of quality, but only very general. In the end, it is the sum of largely subjective ratings with rather subjective weights applied. After all, for one person, ideas might be the most important part of a substance, while another might more heavily weight presentation, density of material, rules use, or some other criteria. And who is right or wrong? Not necessarily any of them. A well communicated review will go further to define if a product is right for you than a one dimentional score could ever hope to.
At any rate, there are specific qualities that I tend to identify when deciding what rating to give a review. The factors I typical consider are: value for content delivered, presentation, system fidelity, utility, and ideas. But again, some of these qualities may be more or less important to the reader, thus the reason why you should read the review.
