Show overview
Modern Mythos with Jon and Seth has been publishing since 2021, and across the 5 years since has built a catalogue of 100 episodes. That works out to roughly 150 hours of audio in total. Releases follow a monthly cadence, with the show now in its 2nd season.
Episodes typically run over ninety minutes — most land between 1h 13m and 1h 50m — though episode length varies meaningfully from one episode to the next. The publisher flags most episodes as explicit, so expect adult themes or strong language throughout. It is catalogued as a EN-language Leisure show.
The show is actively publishing — the most recent episode landed 2 weeks ago, with 10 episodes already out so far this year. The busiest year was 2024, with 27 episodes published. Published by Jon Hook.

S1 Ep 55Ep.55 - Exploring New Adventures
EExorcist'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.
