Want to see how Call of Cthulhu 7th edition fits into Yellow Dawn – The Age of Hastur?

Work begins on migrating Yellow Dawn 2.5 towards a 3rd edition

Last night was my regular Tuesday night session with my game crew. We played Yellow Dawn – The Age of Hastur, naturally.

It’s an RPG that fuses Cyberpunk with Lovecraft’s Cthulhu Mythos in a post-apocalyptic setting.

Recent news for me is that Chaosium have Given Green Light for Yellow Dawn Publishing Deal.  Work now underway to write a 3rd edition of Yellow Dawn adapting it to be used with 7th Edition Call of Cthulhu – allowing CoC players to drop their scenarios into the post-apocalyptic horror and action adventures of my novels.

Incidentally, some other good news is that I had a Hollywood screenwriter approach me couple weeks ago saying that Yellow Dawn would make an awesome movie – so he and I are now working on that as an opportunity.

Last night then, I decided to start migrating some of the core CoC 7e rule mechanics into my Yellow Dawn game. See how they worked. Specifically:

  • STATS as a value between 1 – 100 (rather than YD, which is 3 – 18)
  • New definitions of a Hard, Extreme and Critical success  (rather than YD, which has lots of granularity about different modifiers for different parameters)
  • Introducing the opposed roll mechanics (rather than YD, where players and NPCs both roll under their skills with highest score winning).
  • Spending LUCK points as a permanent deduction to get out of trouble (removing Hero Points in YD, which were a daily pool of points that characters could rely on to influence dice rolls).

It worked really well. I was very impressed how the CoC 7e mechanics allowed the game to take on much more pace and gave me more narrative freedom as GM. The character’s too, did not have their imagination / ideas constrained by having to see how they mapped into a table of different DMs.

One key aspect of Yellow Dawn that I will be preserving is the idea that it is a game of survival.  CoC can be very brutal towards player characters.  I’ll be maintaining the idea of Hero Ranks, and character development through an ascending set of levels / Ranks.

I’ll be handing Mythos magic back to CoC 7e rules but Yellow Dawn has a USP around Occult (non-Mythos) magic, which facilitates the idea of Road Mages (post-apocalyptic sorcerers) and ties in to the sideways evolution of Yellow Dawn – The Age of Hastur, into the product called Dragomir – 10,000 years into the future… (way, way off production but early concept notes are out there).
