I hope you're not feeling like you're being piled on here DeadEarly, as I think this is actually some valuable discussion.
No matter how you cut it, unless they're being untruthful or misleading, their own feelings on the matter is the review.
I don't think a reviewer can communicate if their reader would enjoy the game as they don't know their reader, unless it happens to be a really personal thing. I mean, they can say things like: "If you enjoyed X, you'll likely enjoy this game.", which is certainly valuable. Still, the game has to stand on its own and the reviewer is only able to communicate what they thought about it.Perhaps "objective" was the wrong word to use.
What I meant, was that reviewers should be more concerned with adequately communicating if the reader would enjoy the game, as opposed to their own feelings on the matter.
