## Thesis

Asynchronous shared regions (SimCity 2013) and visits (Animal Crossing) connect players thinly because the other player is absent. Agents that represent a player's interests, constrained by the player's standing instructions, can conduct trade and diplomacy between worlds asynchronously, turning a set of single-player games into a living network.

## Design Sketch

The player appoints an envoy with a mandate (export grain, import steel, never sell land). Envoys meet other envoys in a shared hub, negotiate deals constrained by mandates, and report back with transcripts and outcomes the player can ratify.

## Key Risks

- Agents exploited by adversarial players.
- Mandate violations create disputes.
- Server cost of agent negotiation.

## Validation Experiment

Run 100 simulated player worlds with envoy agents under mandates for 30 days; measure mandate violations, trade volume, and player-rated fairness in a pilot. Success: zero hard mandate violations and positive fairness ratings.

## Falsifiable signal

- **Prediction:** A game will let each player's AI representative trade or negotiate with other players' worlds while those players are offline.
- **Resolve by:** 2029-06-30
- **Criteria:** Feature first shipped after 2026-10-24 in a title with at least 1,000 Steam user reviews or a console release; developer material (store page, patch notes, documentation, or talk) states that an AI agent acts for an absent player in trades or negotiations with other players.
- **Outcome:** open
