ROSE CITY COMIC CON 2025

I'll be honest, I am not prepared for this con. I was fully aware of it for months, but four months turned into eight weeks, that turned into thirty days, and now I've got seventeen hours left.

If I perish, it will be because of my own damn pride.

OTHERWISE, welcome and I'm guessing you are here for Diesel Empires, which is lurking just below...

Upcoming Games

Latest Rules (v30.1.1)

Released: September 5, 2025

Just in time for Rose City Comic Con. Not much different from v30.0.0, but I did change how damage works, and modified the wording of the Check outcomes.

The Kings Mart versus The Gray

COS ELIAS, 22-1992. It's the summer solstice, so the magic is bigger, and the parties are harder. Your faekind boss, Alice, always throws a legendary celebration to kick off the new year, and the delightful surprise this year is a visit from an unknowable creature plucked from the vast, cold void.

Tom Eldion’s Auto Sales at the End of the World

CE-2243 TAU GATE. It’s not easy selling cars in Tau Gate, especially with a Fae resting in the heart of the city, and competition that is just as deadly as your team. Luckily Tom is a good boss, and he trusts you to keep the lot safe with everything you got: magic, guns, and legal ambiguities.

The Kings Mart versus The Endless Sons

BETELAHR, 22-1986. The War rages at the border, but the market for chips, bargain magic, and faux-elven wine has spiked. Corporate is paying you a LOT to stay open in a conflict zone, but you weren't expecting an ancient evil to be awakened in the parking lot. Tonight's extra job: save the city.

Kingdoms of Ash: The Three-Eyed Crown

THYEDHAER PLAINS, 5TH YEAR. You are knights with no banners and no kings. You travel with the elf seer Asholk because she is the only voice bringing order in the Aftermath of The Fae. This path is costly, and in the lands of the Three-Eyed Crown, you must pave it with either diplomacy, or blood.

Rulesets

v30.0.0

Released: February 25, 2025

Everything I loved about v29.4.4 with an addition that I saw players attempting to do several times, and I liked the concept: Core Traits don't automatically start at one, but during a Check, you add one Core Trait with one Background Trait to get your starting draw. I think it makes the Core Traits more powerful, and makes how the players use their characters more unique (I hope).

v29.4.4

Released: January 10, 2025

So far v29.x is a winner! At least for my style of play. Still some things I need to fix about weapon damage and key traits. I like where v29.4.4 is going though...

v29.4.3

Released: November 27, 2024

This version adds in some refinements to v29.4.1 and changes up some of the terms to make more sense. What happened to v29.4.2? Maybe I'll tell y'all about it when you get older...

v29.4.1

Released: October 18, 2024

Oh boy I am SUPER excited for these rules! Let's see how they do in real games now...

I'm also experimenting with the player handouts so I can drastically reduce how much paper I use.

v29.4.0

Released: October 12, 2024

These rules premiered at a private con and oh boy did I have fun! I have this sinking suspicion that this might be approaching the final form for the game. v29 has been my most favorite version.

v29.3.2

Released: August 23, 2024

This is the ruleset that I will be bringing to the 2024 Rose City Comic Con. There won't be any "Bad Night" games, but I added the playbook since they were part of playtesting.

v29.3.1

Released: July 29, 2024

This was for a one shot called "Bad Night in Bonethorne Port". Experimented with a new combat system and a new way to approach checks.

v29.2.0

Released: March 3, 2024

v29.1.0

Released: January 11, 2024

This still uses the v29.0.0 core sheets.

v0.0.1 (Turn of the Card Edition)

Released: May 5, 2022

This one is a remix for another game I produced with my good friend Paul Abeyta. It can be found at TurnoftheCard.com.

v24.2.0

Released: January 28, 2022

v1.4.0 (First Edition)

Released: February 16, 2020
