I was surprised to be able to pick up the two Northern Crown books for the knock down price of £9 each while on a trip to Bristol. I thought the idea was okay (d20 fantasy Colonial New England) but clearly it must have bombed on the market.
A quick flick through the books does reveal a lot of flustering around the whole d20 thing but there's only a few companies that actually do it right anyway. Certainly the material on North American folklore beasties seems alright to me.
More as I get into the books in more detail. Personally I am looking for a kind of cross between the back story of Blair Witch and Sleepy Hollow.
