The lack of reviews is due to a couple of factors, I think. First is people are buying fewer games. Or at least that it is impression from the recent poll on these boards. Second, there seems to be a group of dedicated reviewers (psion and the rest of the ENWorld people, the D20 Magazine Rack review board). These people can write good reviews, and people reading reviews begin to expect this level of a writing in a review. I know I can't write reviews to the standard set by these people. Partly because I don't have the depth of D20 knowledge and partly because I just can't write that well without a lot of work.
