This article is a rather nice look at the online gaming media outlets (amazingly Monkeygames was not listed ;p) and how they rate with respect to each other on their ratings.

I have always been a little skeptical of sites that are clearly deriving their revenue from game reviews, and have often wondered at their impartiality. Though, it seems that overall you can get a fairly clear picture of a game when you put 2-3 sites in your game browsing rotation. How refreshing.
