I have to agree - RPGNet is a cesspool. I don't go there very often, and that thread only reminded me why.
I just got my copy of the "new"
H.P. Lovecraft's Dunwich supplement for1920's
Call of Cthulhu from Chaosium. I say "new" but, as most of you probably already know, it is for the most part a reprint of their earlier 1991 version of the book. This time around, however, it features dual stats for both classic CoC and d20 CoC. The d20 CoC stats are in the back in Appendix 3.
Now I've only had this about a couple of days, but at face value the d20 stats and conversions look good, or perhaps I should say "legit". Here you will find d20 conversions of all 35 NPCs in the book, the new creatures (the Son of Yog-Sothoth, Abhoth, and several Children of Abhoth), and d20 conversion notes for the new spells found within (some of which already exist in the d20 version of CoC, so you are referred to that text). d20 fans who favor crunch to fluff be warned, however: this book is heavy on the fluff, light on the crunch. And as well it should be, considering what it is.
I highly recommend this book to anyone who loves d20 CoC but may not be familiar with Chaosium's products. This is Golden Age Chaosium - Dunwich is a richly detailed setting and you will probably get hours of use out of it. I have long been a fan of their other sourcebooks that feature Lovecraftian locales like
Escape from Innsmouth and
Arkham Unveiled. I really look forward to the dual stat reprints of these as well.
Patiently and eagerly awaiting
Pulp Cthulhu,
