Fourthmarches RPG is a weird-fantasy open-table RPG about exploration and rediscovery using the Year Zero Engine.
In the game players...
- explore iteratively, delving into strange sites
- try to survive the elements, animals, and oddities of the Fourth State
- flesh out pregens and make them their own
- follow a four-phase game structure and try to get home before end-of-session
- form cohesive parties or play with rotating casts
- gamble with empowering RESONANCE and possibly lose themselves to it
The setting includes...
- societies across a continent emerging out of uncounted centuries of instability
- the ancient cause is RESONANCE, a phenomenon your employer is trying to stamp out
- its empowering and self-dissolving effects
- most large fauna wearing their skeletons on the outside (such as the manticore, pictured below)
- the scarcity of extractable metals and the consequences for weapons, tools, and value
Free Quickstart is here.
The game follows many OSR principles with strong NewSR vibes.
