I've found that some of the best game reviews come from those who DON'T do it all the time (as well as those found in publications not normally known for games coverage). They come from a fresher point of view than a reviewer who reviews games as his or her job and may have become jaded. Now, is this always the case? Definitely not. Sometimes the expert reviewers have insights that newer ones do not. Sometimes the newer ones miss out on stuff or don't know the whole scene very well. I still think some of the best reviews are from those who don't do them all the time, though. At the very least, these reviews are of a more 'honest' bent because they tend to have fewer preconceptions about the game beforehand.
Of course, this is all my personal opinion based on my own personal experiences. I'm sure many of you have experienced this differently. I just wanted to mention it, though, because I did like this guy's review.
