This is a downloadable PDF rulebook.
It is played with your existing AI model—not inside a browser, and not as a conventional video game.
Operational concept
Choose any country as it existed in 1946. Each turn advances one season—four turns per year—while the world continues moving beyond your borders.
Your AI becomes the geopolitical simulation engine, adjudicating politics, economics, conflict, technology, culture, and the compounding effects of policy.
Depart from history and a new timeline forms. Other nations retain their own ambitions, react autonomously, and remember your past actions.
The book supplies the rules, systems, and consistency framework. The model serves as a neutral referee rather than an ally, opponent, or storyteller on rails.
Field procedure
Receive the complete PDF rulebook immediately after purchase.
Upload the PDF to ChatGPT, Claude, Gemini, Grok, or another capable LLM.
Select any country as it existed in 1946 and set your difficulty.
Investigate, negotiate, and issue orders. End your command with “End Turn.”
Keep a simple ledger of treasury, revenue, expenses, and lasting national conditions.
You must supply access to your preferred AI model. A paid AI subscription may provide longer context and more reliable multi-decade campaigns.
Sandbox
Maximum latitude for counterfactual play and improvised scenarios.
Historical Realism
Decisions are tested against the hard limits of the period.
Murphy’s Law
A severe campaign where friction, chance, and unintended consequences compound.
Rulebook dossier
A historically grounded baseline for any nation, including colonies, occupation zones, and governments-in-exile.
Systems for institutions, ideology, public opinion, political authority, diplomacy, and domestic power.
Treasury management, revenue, expenses, infrastructure, trade, development, and strategic resources.
Mechanics for cultural change, migration, living conditions, legitimacy, and social pressure.
Rigorous prompts that make the model remember consequences, test plausibility, and keep rival nations autonomous.
Three difficulty modes and guidance for carrying a divergent timeline across decades into the modern day.
Designed for the serious player
Built for enthusiasts of history, economics, diplomacy, and deep grand strategy—from Victoria and Hearts of Iron veterans to readers of serious alternate history.
It is unapologetically complex, simulation-focused, and designed to reward informed decisions over spectacle.
Content advisory
This adult geopolitical simulator engages with real historical dynamics, war, crisis, ideology, and state power. Referee instructions call for moral neutrality and realistic consequences without preachy framing.
