About this game

Watch a World Become History

Things That Happen on the Map - Realm Simulator is a world sandbox where countries, cities, families, and individuals create histories through interacting systems.

From Maps to Individual Lives

Zoom out to follow rising powers, wars, alliances, and shifting borders. Zoom in to trace a city, a family, or an individual across generations.

A Living Simulation

  • War and diplomacy reshape borders and power.

  • Economics and politics drive the rise and decline of cities and families.

  • Characters, culture, and geography connect individual lives to larger historical changes.

Small events can spread through these systems and eventually change the fate of an entire region.

Stories in a Changing World

A memorable story may be a city that outlives its country, a family that rises and fades, or a border that quietly disappears over generations.

Active Development

The game is currently in early development. Its systems, content, balance, performance, and interface are still evolving.
