    The Keeper companion is a great book for both new and old keepers giving new idea and Optional rules to use to help players and yourself out a bit. The new sheets are very nice and the new rules work well with the system and are optional you don't have to use them if you don't want to. The Artwork is top notch as always and the 3 included Scenarios sound fun (can't wait to run them)

    I’ve been playing Call of Cthulhu since 1982 and I’m fond of the BRP system in its many iterations. Despite all these years, I was very excited by the release of this Keeper Companion and its promises of optional revised rules. After reading, I would give it three stars out of five. The adventures look interesting. The chase rules are welcome. Broadly speaking, the Alternative Investigator Creation and the Game System chapters provide some interesting ideas, but I must admit I expected more. I’m fully aware of the fact that mofifying a classical RPG like Call of Cthulhu isn’t easy, so I won’t complain about these chapters. However, I’m deeply disappointed by the Sanity chapter and the choice to use « Changed » instead of « Insanity ». It sounds so dumb to me and so revealing about the editorial policy of Chaosium. The text box page 85 says it all, as do this « X-Card thing » and this obsession for inclusivity in the artworks. I’ve already had that thought, but this book is the last straw for me. Release after release, I have to the conclusion that this 7th edition isn’t for me. I’m done with it. I’ll stay with the previous ones. I long hesitated to write this review because I know it won’t change the way of thinking of the authors, but as a faithful customer for years I think I needed to tell what’s on my mind.
