# Kinbarrow

> Kinbarrow is a fantasy RPG in which the realm is simulated. Villains make plans and every coin in the economy is accounted for. Realms are rolled from a seed, and the same seed gives the same realm. One copy per table. In development.

The markdown twin of https://kinbarrow.com/: the same facts, without the layout.
Kinbarrow is a single-developer game in development, fully compatible with D&D
5e and 5.5e rulesets. The realm is simulated rather than scripted, and everything the game loads is a
data file a mod can replace.

## What it is

- A fantasy RPG whose world keeps running when you are away. Purses,
  schedules, wills, guilds and wars are all simulated; none is placed by hand.
- No quest script in the engine. The stories on the landing page came out of
  the simulation.
- Solo by default; one purchase per table, on Steam, with friends joining a
  hosted realm for free. Not yet released, and no announced date.
- Fully moddable: see the reference below.

- **Can I play alone?** Yes.
- **What will it cost?** One purchase per table, on Steam. Friends joining your world never pay.
- **Is the world AI-generated?** No. Everything in the realm comes from a seeded generator and a simulation, both ordinary code.
- **What do I need to run it?** A reasonably modern PC. Exact specs will come closer to release. The engine builds on Windows, Mac and Linux today.
- **What can be modded?** Everything the game loads is a file you can edit. The [modding reference](https://kinbarrow.com/modding/latest/) lists every field.
