Reviews do have an effect on game sales.

How many times have you read a review topic on VG Chartz where someone says "Okay, this game just went from a possible buy to a definite/must buy for me!" I've read quite a few of those statements.

There are definitely a number of fence-sitters out there that look at reviews to be the deciding factor.

 Exactly, I was on the fence about Lair until the reviews said it was utter crap.
