This is NOT the original, percentile-dice-based Basic Role-Playing System version of the rules, but rather a port of Dungeons & Dragons' 3rd-Edition D20 rules set. I would rate the original version (the one currently published with the blue cover) higher at 5 stars - the original BRP system is very simple to learn and very nicely suited for the Call of Cthulhu RPG, and is the better of the two systems for a Call of Cthulhu game. I don't care for the more complicated D20 rules in this game setting (I think they are better suited for D&D than for CoC), but the full-colour artwork in this version is beautiful and genuinely creepy, the production values over-all are top-notch, and the Keeper (Game Master) advice chapters for running horror RPGs are very nicely presented and fascinating to read. At the very least, this version makes a great reference book for any RPG with a horror theme (especially D20 games like Dungeons & Dragons), and, though I prefer the classic rules system, this D20 version would present virtually no learning curve for the rules set for anyone used to the D&D 3rd Edition rules system.

This book is one of the best books released using the OGL, far better than d20 modern.

I've only had a few opportunities to be exposed to the Call of Cthulhu system; however, all of the interactions I've had have been amazing! Be creative with this system. The best part is -- the system is really simple! Anyone can play. It's the perfect game to get your friends into role-playing games.

This is one of the best RPG I have played... I been playing DnD for quite a few years, and I loved H.P. Lovecraft Books since a long time ago... I recently discovered this book and started a few campaings... and I loved it... so now I am buying the book to start being GM, I read the book on the web and it is wonderful... I recomend it
