I working on an idea for a Pathfinder campaign I am trying to figure out how to do it. I know few of the classes would fit in that type of world ie Gunslinger, Alchemist, Investigator, Vigelante, Witch, Monk, Ranger, Slayer, Hunter and Druid.
Steampunk is full of pulp concepts, so almost anything can be part of a cult.
Check out Pure Steam's Westbound. Just released. It is literally a Western Steam Punk Setting. No PDF version as of yet, though. I helped Kickstart it and the book is awesome!
I recommend Pure Steam as well.
Dunno, I was part of a, too brief, western game, and the classical med fan classes worked fairly well, as did the advanced firearms with the 'guns everywhere' rules... of course, the whole steampunk weird tech aspect was absent, though steam tech (trains) was present.
Heya dudes. The Westbound PDF can be found on Paizo's site, DriveThruRPG, and Open Gaming Store.
In Westbound, we have Western-themed archetypes for the alchemist (a snake oil salesman), the barbarian (a native-american themed "brave"), the bard (a gunslinging bard), an order and archetype for the cavalier, two archetypes for the gunslinger (a charisma-based one, inspired by The Mariachi/Desperado; the other a knife-slinger inspired by the Magnificent Seven), the magus, the monk (inspired by the gun clerics in Equilibrium), ranger styles and archetype (cowboy inspired), a rogue archetype (a train hopper), and some witch hexes revolving around gunpowder, firearms, and technology.
We've also designed a new base class, the Marshal, a gun-slinging lawman.
Check it out!
