I got Call of Cthulu D20

Yes its D20 and could never live up to Mr. Lovecrafts ideals but it is very cool and might just add flavor to any one of the myriad campaign ideas i have rattling around in my noggin. Ravensfae, the "Hounds of Tindalos" are gross. "Nightgaunts" are very cool. The magic system is very cool, no level limits, no memorization, once you learn a spell you can use it whenever you want, but it will probably drive you nuts as it slowley weakens you, very cool. It has a few pages for D&D 3e conversion so to me it's universally adaptable.
