Today we’re talking to Antonio Marchena, Matt “Doc” Tracy, and Evan Perlman.  Antonio Marchena's very first published scenario is THE HOUSE OF FLESH, a modern scenario that emulates the kinds of horrors seen in movies like The Texas Chainsaw Massacre and The House of 1000 Corpses.  Doc Tracy authored MOTHER, MAIDEN, CRONE, a scenario of difficult choices set in the 90's.  Evan Perlman partnered with Heinrich Moore as...

More Episodes

Exorcist’s Codex

2025 by Two Starving Gnolls (Pax Cthuliana, Svasbard - system-neutral adventures)

Uses BRP mechanics (with ORC License)

1890s Demon Hunters

Mechanics

  • Several Occupations - Occupations offer special abilities, restrictions, and modifiers to Faith (Relic Hunter, Priest, demonologist, occult detective, Church Licensed Exorcist, etc)

  • Holy Faith Factor - source of Power, but higher it is the more susceptible to Demonic Corruption

  • Instead of SAN they Have Spirit - works very similar, but one key difference is that it replenishes with time. Speed based off how low it is. Spirit can be spent to inf;uency Destiny Rolls (sorta like Luck rolls)

  • Criticisms - I dislike BRP Resistance Table. Feel the 7e CoC should have been used for BRP, but they chose not to. Unsure on diversity of adventures. But I haven’t read too deep. 

 

Indiana Jones RPG

1984 by TSR (David Cook - game designer)

Uses Percentile dice for Attribute Test resolutions

Setting: Pulp 1930s pre-war

Mechanics

  • Attributes - All characters have six attributes: Strength, Movement, Prowess, Backbone, Instinct, and Appeal. 

  • Each Attribute has four percentile values: Normal, Twice Normal (x2), Half of Normal (1/2), and One-Quarter of Normal (1/4). 

  • Referee (GM) determines the difficulty of an Attribute Test, and then the player attempts to roll percentile dice equal to or less than the declared difficulty level. 

  • Characters have Skills, but no skill has a percentile value; instead having an appropriate skill, (or using a skill in a clever way), can influence the difficulty level of an Attribute Test, typically making it an easier test if the character possesses the needed skill, or possibly more difficult if the character does not have the needed skill.

 

We can’t do this show alone. We want to thank our amazing editors Max Mahaffa, Edwin Nagy, and Zach Sokol for their hard work and keen skills at making us sound awesome! 

We also want to thank John Sumrow, for our badass logo. He’s a very talented artist, so please follow him on Facebook, check out his official website,  and please consider joining his Patreon account. Links in the show notes.
