Very pleased with the PDF. I would have given five stars but there is a 17x22 map associated with this title and it's not included or mentioned as part of this listing. Wish I'd realized that before ordering. If you want the map as well, you'll have to order it on Chaosium's site instead.

My favorite RPG is Call of Cthulhu. This supplement gives the GM amazing background to run the players through one of most interesting cities of Lovecraft's New England. While I still love the older version of CoC, the d20 version is a great way to get players, including younger players, introduced to a unique RPG. Dunwich should be part of anyone's CoC game. Even if you don not play CoC, but love to read Lovecraft or play other games, you should pick this up. Gives you nice atmosphere!
