Oncin: Universal Simulator

Create the world. Live inside it. See what it becomes.

Oncin: Universal Simulator is a persistent roleplaying and world simulation experience for stories that do not belong to any single setting.

Built on the ONCIN architecture and gameplay systems used across ONCIN simulators, Universal keeps the persistent world simulation, evolving characters, consequences, Status, Codex, Archive, Atlas, Gallery, Campaign Lore, and creator tools players already know — but removes the predefined universe.

There is no predetermined world you are required to enter.

Instead, you decide what the universe is.

Create a medieval kingdom, a futuristic civilization spanning several star systems, a quiet modern town, a hidden supernatural society, an alternate history, a superhero world, a post-apocalyptic wasteland, a strange metaphysical reality, or something that does not fit neatly into any existing genre.

You can arrive with an entire setting already imagined, or begin with nothing more than a simple idea.
