Are you agreeing with Drek that a game reviewer should review games based on what he thinks his audience will think of the game, while ignoring his own opinion?
Earlier, you said that you thought reviews should be more than just personal opinion. But what else can a reviewer add that is in any way honest? The way I see it, a well-written game review basically is a standardized sort of editorial on the quality of a particular game, and what sets a reviewer apart from, say, a blogger is their ability to present their opinion in a way that gives the reader a sense of why they felt the way they did, while still giving people with other tastes a sense of what the game offers.
A review can't really encompass another person's perspective, and any review that attempts to do that really has to be, in some way, dishonest, because the only thing the writer can be certain of is their own views on the game. Reviews with an eye towards objectivity have to value the objective characteristics of a game more (things like length and production values) than how they personally feel, because those objective things are the only aspects of the game they can be certain all audiences will experience equally.
