• An array of historical and fictional material to help you create exciting player characters and NPCs

• A background generator, designed to help you find out what dark secrets your past contains…

Will you update this for Savage Worlds SWADE as well? Also will it be a Call of Cthulhu 7th edition update only, or also a Pulp Cthulhu update?

Currently we're just planning an update to CoC 7th Edition.

Will that be a new release or an update to this? It's your decision of course but updating existing Savage Worlds material to the SWADE version is just minimal work. Pinnacle will also provide upgrade guides (probably for publishers as well), and with the new release, there will be a lot of people interested in SWADE material.

Alright, What in the world is up with the price of the physical copy of this book? The Keepers guide goes for anywhere between $30-$50, while the lowest price I found for this a $500!!! And the higher price was over $1000... What am I missing?

It's been out of print for a while, and with a new 7th edition planned we're not planning to reprint the 6th edition version

Can this version be used with 7th edition of Call of Cthulhu ?
Customer avatar
Chris B January 27, 2017 2:04 pm UTC
Yes - 7th edition includes a short section on converting 6th edition material, it's really very simple.

When it means compatible Call of Cthulhu 6th edition and savage worlds, does that mean I need one of those systems to play this or is it completely compatible on its own?
Customer avatar
Chris B January 18, 2016 9:02 am UTC
Yes you will need a copy of either the Savage Worlds core book or the Call of Cthulhu 6th edition core book

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
