Sionnach Games is an independent tabletop roleplaying game studio focused on strange worlds, strong atmosphere, cinematic play and systems built to support the stories they promise.

Who We Are

Sionnach Games is an independent tabletop RPG studio based in Ireland, creating original games with distinctive worlds, accessible systems and a strong sense of identity.
We like games that feel alive at the table.
That means memorable settings, impactful character choices, mechanics that support the fiction, and enough flexibility for players and game masters to take the story somewhere unexpected.
Our goal is to:
Make games that are easy to step into, hard to forget, and fun to build stories around.

What We Make

WORLDS WORTH EXPLORING!At Sionnach Games, setting and system are built together.
We are interested in worlds shaped by strange history, folklore, technology, mystery and consequence; places where the atmosphere of the setting matter just as much as the rules on the character sheet.
Our games are designed to support:
- cinematic storytelling
- impactful choices
- character-driven narratives
- exploration and investigation
- action with consequence
- flexible campaign tones
- worlds with their own identity
Whether a game leans toward science fiction, horror, folklore, mystery or pulp action, the aim is always the same:
Give players somewhere they want to stay.
