Independent studio · Lake Constance, Germany
We build worlds. To play, to read, to tell.
Strategy games, novels and a tool for game masters – at ReSim Studio everything grows out of the same worlds. Pick your way in.
Three ways in
Play. Create. Read.
Whether you build a realm, lead your group into a crypt or wake up with Konrad and Johan on a foreign beach: the stories are connected.
Frontiers of the Realms
Settle the borderlands of rival kingdoms, build production chains and play your deck in simultaneous turns.

Our game
From your first village to a realm of your own
In Frontiers of the Realms you explore a hex map of forests, mountains and coasts, found settlements and link workshops into production chains. Everyone moves at the same time – and your card deck decides which path your realm takes.

Our tool
Kartil puts the map on the table
Kartil is the tool we wanted for our own game nights: build maps in minutes, then show them on a second screen or in a browser while you stay in control.
- Rooms in one goFloor, walls, doors and furniture are created together – with generators for dungeons and caves.
- Fog of warLine of sight, doors and torches decide what your players see.
- For you and your AIEvery feature is also available through a local API and an MCP server.
