Big Update! - Tcho Tcho's - New Designer Pledge - and Pathfinder HORROR Adventures!


Tcho-Tcho Day!

Best Day Ever! 

Especially if you’re a Great Old One.

Originally an Asian tribe from Earth. Tcho-Tchos have worshipped Great Old Ones for thousands of years. Their dedication to the Great Old Ones has warped their minds and souls over the centuries.  

When we unlock this stretch goal the book will include information on the morally debased Tcho-Tchos, their evil ways, unspeakable magics, and the secret behind the meat they call “pork”.

New Designer Pledge!

As the designer for this pledge you join the inner circle and learn the meaning behind the name GOBOGEG.  

This handsome fellow needs to be brought to life. What are his powers and relationships to the Great Old Ones? We have some unique ideas for Gogogeg, but we want to hear yours! This is a special being and one lucky backer will get to join Sandy to work on him.

This model sports a HUGE BASE, and stands almost 5" tall!

Ian plays the New 'Horror Adventure' From Paizo

Last week, while at the GAMA Trade Show, I had the privilege to be the first people outside Paizo office to play with the new Pathfinder Horror Adventures. Our Gamemaster was none other than Jacob Bulmahn, lead designer of Pathfinder at Paizo Publishing. 

It was great fun! Jason is one of the best Gamemasters I’ve ever experienced. Certainly the best I’ve played with in a public setting like GAMA. 

For those unfamiliar with Horror Adventures, it’s Paizo’s book on adding spookiness and horror to your Pathfinder game. It’s scheduled to come out later this year. 

While the book included no new classes or creatures, it does have a number of other interesting new rules. 

One of the cool rule sets adds four more conditions to the existing Shaken, Frightened, and Panicked states of fear. Spooked, and three others that are even worse than Panicked that Jason explained to us. 

We played Horror Adventures’ new rules for sanity and madness. These straightforward rules are easily implemented. They will be very comfortable to someone who has played the sanity rules in the Call of Cthulhu Role-Playing game published by Chaosium, and originally written by Sandy Petersen. 

Another feature we tested out was corruptions. Corruptions are basically an affliction (such as vampirism, lycanthropy, lichdom as well as others) that has been bestowed upon a player character. Unlike the normal rules for such things, these rules allow the PC to be affected by the corruption a little and then progress at the player’s choice. Becoming more corrupted leads to having more abilities, but also leads you closer to your character being completely corrupted, evil, and therefore according to these rules, given to the GM to become an NPC. 

There are additional rules in Horror Adventures for other things, including curses and diseases, but we did not play those. 

With the exception of insanity rules, Petersen Games’ new book Sandy Petersen’s Cthulhu Mythos for Pathfinder does not appear to conflict with the rules in Horror Adventures or visa versa. Sandy Petersen’s Cthulhu Mythos for Pathfinder is expertly focused on the Cthulhu Mythos while Horror Adventures is more of a wide spectrum, general book on Horror. 

The rules for insanity in Sandy Petersen’s Cthulhu Mythos for Pathfinder are a little more in- depth, and are specifically in-tune with the writings of HP Lovecraft, compared with those in Horror Adventures which are more broad-based. Plus, in Sandy Petersen’s Cthulhu Mythos for Pathfinder, insanity can have its benefits. 

Sandy Petersen's Cthulhu Mythos for Pathfinder will be the definitive guide to adding Lovecraftian horror to your Pathfinder game. Horror Adventures can add excellent rules for spookiness and character corruption to your toolbox. 

You do not need either one of the books to fully use the other. They are compatible, not interdependent. 

In summary, I highly recommend Horror Adventures

      That is AWESOME, Sandy. Thanks so much for sharing your experience with Horror Adventures. I'm even more excited for this project (if that's possible ). Your energy and enthusiasm is greatly appreciated!!! ☺

      I bought Occult adventures and was already planning to pick up this one. It will be interesting to see how the pair interact with one another. As it stands now, your book is coming out too late to use at the upcoming Halloween themed furry convention I plan on attending this year but I can probably use the book for next year along with Occult and Horror adventures. For me, someone that played in Ravenloft and loved it, this is a no-brainer. Now granted Ravenloft did not have a strictly Lovecraftian section, I now think it should have but that's my opinion after getting to know the dark wonder that is Lovecraft, but I will be getting that itch scratched this year. This is just one piece of the puzzle. And I am glad to have itt.

      With all due respect, I believe the plural of Tcho-Tcho is also "Tcho-Tcho."
