Latest Updates from Our Project:

Closing the Pledge Manager + Survey Link!
over 1 year ago – Tue, Nov 22, 2016 at 06:39:11 PM

As we said in our previous update, we are closing the pledge manager today, November 22nd at 9:00 PM PST (midnight EST).

What does this really mean?

This means we are charging your card for Shipping (plus any upgrades or add-ons you've selected beyond what you pledged for during the KS), IF you have confirmed your pledge. 

If you have NOT yet confirmed your pledge, then your card will not be charged. We will try again next week (we'll let you know), to give you a chance to finalize your pledge. 

IF you did not read this in time, and your card is charged because your pledge is confirmed in BackerKit, but you but still wanted to add something (such as the collector's editions, which people are still scrambling to get!), then you can email support at petersengames dot com and James will take care of you. All is not lost! Your pledge can be Reincarnated. (James is a Druid).

If you can't find your survey, you can get a new link by clicking here. Yes, Right Here!

Closing the Pledge Manager + a few misc. updates!
over 1 year ago – Sat, Nov 19, 2016 at 09:03:06 PM

Transmission with Brain Cylinders Reconnected.

Our normal Monday update (for November 14th) has been moved to the end of this week due to an error in the signal (it can take quite a while to send from far Yuggoth, after all). Also, we’d been waiting for some major news which we didn’t get until Thursday of this week.


We need to close the pledge manager so we can get the final count to the printer. So it’s IMPORTANT you upgrade your pledge to the COLLECTOR’S EDITION (if you are doing so) in the next few days.  

We are closing the pledge manager on November 22nd at 9:00 PM PST (midnight EST).

This means now is the last time your friends can jump onboard and get all the freebies, etc. with this Kickstarter. We’d appreciate it if you’d let folks know.


As you know, there are plenty enough of you that wanted the COLLECTOR’S EDITION with the leather cover and hand signed by Sandy Petersen that we’ve offered it at the $7.57 as promised.

A few of you have expressed difficulty in understanding how to do this upgrade. Here are the directions again, including upgrading from a PDF to the COLLECTOR’S EDITION. If these directions aren’t doing the job for you, then just email and we will get it sorted with you personally.

If you currently have a regular edition selected in the pledge manager, but want a collector's edition, all you have to do is simply select the upgrade add-on for $7.57 and you’re done! If you have this upgrade, the regular edition will not be sent to you!

If you are only getting a PDF, but want the physical Collector’s Edition, you will need to first change your pledge level to a pledge level that includes a physical copy. Then, simply select the $7.57 upgrade as an add-on.


First, dispensing with the unpleasantness. We’ve always planned on shipping the book with the miniatures. The miniatures won’t be landing in the USA until February. We’ll know the exact date when it gets closer.  

So, given we have a little extra time, we’ve decided to expand the book’s content as a thank you for being patient. How much are we expanding it? – OVER 20% more content! This is a big upgrade. As a smaller publisher, we have the discretion to do cool things that increase our costs and lower our margins. So we are. Plus, Sandy Petersen’s Cthulhu Mythos for Pathfinder is the definitive book on this subject for Pathfinder. So adding more content just felt right. (Also, when we give Sandy target word counts for sections, he keeps creating such amazing content that we'd prefer to not cut him off! Seriously, we didn't even know he could make something as simple as Zoogs be so awesome!).

The major news that we got Thursday comes from James Jacobs, creative director at Paizo Publishing. As one of the authors on Sandy Petersen’s Cthulhu Mythos for Pathfinder, he has agreed to write a whole new section for the book on Deep Ones under Sandy’s purview. This will cover many variations of hybrids, how to create additional hybrids, mating habits, and more.

We don’t want to give away everything we’re adding (yet – we’ve got to save some things for future updates) but another thing you’ll see in the increase in volume in detail on many of the creatures.

Again, we apologize for our weekly update being at the end of the week instead of the beginning.  

Thanks again for all of your support and encouragement!

Collector's Edition Live!
over 1 year ago – Mon, Nov 07, 2016 at 09:58:14 PM

You VOTED and YOU WON!  

We’re excited to announce that the Collector’s Edition of Sandy Petersen’s Cthulhu Mythos for Pathfinder is available to pre-order! Well over half of you answered the survey from last update, and more than half of our total backers told us they wanted this!

Starting now you can go back into the Pledge Manager to upgrade your copy of Sandy Petersen’s Cthulhu Mythos for Pathfinder from the standard copy by simply selecting the "upgrade" add-on. This add-on has $0 shipping (since it costs the same to ship both versions of the book). You'll still see the regular copy of the book in your rewards, but if you have selected the upgrade, you will not receive the regular book - we will manually remove the regular book and replace with the collectors edition if you have selected the upgrade. We will do this after exporting the data. (If you have more than one copy of the regular edition, we'll only ugrade as many as the number of upgrade add-ons you've selected. 

Many of you expressed a wish of keeping your standard edition for daily use and getting the Collector’s Edition for posterity (and, of course, awesome bragging rights). This will be possible. If you still want your regular copy, but simply want a copy of the Collector's Edition as well, then get the Collector's Edition itself as an add-on (this will cost shipping, but not much at all). No matter if you’re getting one or many Collector’s Editions, you’ll be totally thrilled you did. 

 I want to give a personal shout out for Sandy and the rest of the crew for pursuing this initiative so we can offer this incredible book with a Collector’s Edition option at such an affordable price. 

 It really is Sandy’s and the whole gang at Petersen Games way of saying THANK YOU to all of you for being so awesome and for supporting getting this momentous book published.

Collector's Edition book (leather + signed by Sandy!)
over 1 year ago – Tue, Oct 25, 2016 at 08:05:15 PM


We have been mulling over an idea for a while and want to unleash it upon you like a pack of angry zoogs. 

This book is intended to be the ultimate source for introducing and using elements of Lovecraft's Cthulhu Mythos in Pathfinder, as interpreted by Sandy Petersen - the godfather of Lovecraft in gaming and innovator of many Lovecraftian concepts and entities that have become Mythos canon. Such a definitive work on Mythos horror deserves a Collector's Edition. 

For an additional $7.57 you may get Sandy Petersen’s Cthulhu Mythos for Pathfinder upgraded to the Collector’s Edition that has foil stamped leather covers and is hand signed by Sandy Petersen. You are also eligible buy extra copies of the Collector’s Edition for only $43.26 each.

This is a LEATHER (not the ‘leatherette’ or ‘faux’ leather) cover. Our manufacturer says you’ll literally be able to smell the difference because of that true fine leather aroma. + Beautiful foil stamped covers. + Hand signed by Sandy Petersen. These are NOT machine signature duplicates. This is the real thing.

Petersen Games has researched and found a leather + foil stamped option that’s both awesome and affordable. The main reason it’s affordable is NOT any cut in quality, but rather NO mark-up for these additions! Insane on our part – well yes. But we’re talking about Cthulhu Mythos – so some insanity should be expected. Seriously, this is a once in a lifetime opportunity. We want to make it super affordable for all.

Here's the catch on us offering this:

We need a limited number of orders to do this, or else the cost is much greater. If we get orders for 540 (or close enough to it) we can offer the leather versions of Sandy Petersen’s Cthulhu Mythos for Pathfinder. The message here is – if you want it, order it.

You’ll be receiving a survey shortly (in another update) that asks if you want it and how many you might order. This isn’t a commitment. It just gives us a feel for the interest level. If the interest level is high (and we expect it will be) then we’ll add it to the pledge manager and send out instructions on how to add the upgrade to your order and order additional copies.

Importantly, after this last eldritch process, we will be closing the pledge manager down soon after, and charging everyone's cards. We will give you a precise date that will happen so there are no surprises. 

Pictures and more pictures. Here are some of the pictures we’re using in the playtesting of the Campaign Launch Adventure. We’re still tweaking it and should have the maps done soon so we can send it out to the Beta Test groups.

Collector's Edition Survey!
over 1 year ago – Tue, Oct 25, 2016 at 07:26:04 PM

Here's the survey, as promised in the previous update.

As previously mentioned, we're offering the Collector's Edition upgrade at cost, so price is not a barrier to anyone.
