## How it works

Diplomacy uses promises, exchange and threats to change other powers' behavior without immediate combat.

## Variants

### Mechanic variants

<a id="t075-variants"></a>

- Treaties connect benefits to obligations. <a id="t075-v1"></a>
- Guarantees involve allies in future conflicts. <a id="t075-v2"></a>
- Sanctions change the cost of enemy trade. <a id="t075-v3"></a>
- Reputation limits trust after broken promises. <a id="t075-v4"></a>

## Design example

Port access is paid for by protecting a trade route through a disputed strait.

Prototype check: Test whether players understand when a treaty activates and the consequences of breaking it early.

## Context and limits

Strategy connects production, territory, information and long-term commitments against an uncertain opponent. Each overview separates player actions, state changes and alternative rules. Examples are hypothetical design scenarios, not claims about a named game. A prototype check states an observable question for the next iteration. Existing detailed references remain separately linked from the direction map.
