About Doctrine

Doctrine is a geopolitical simulation spanning 1990 to 2050. Take charge of a major or minor power; navigate post-Cold-War alliances, manage economic and military doctrine, and respond to procedurally generated crises. Aerobiz-style decisions on a real d3-geo world map.

How to play

Quarterly turns. Each quarter: review intelligence, set foreign-policy posture, allocate military and economic budgets, respond to crises. Non-deterministic events (recessions, civil wars, climate shocks) inject realism. Win condition is open — accumulate national capability score across the full 60-year campaign.

Frequently asked questions

How accurate is the geopolitics?

Doctrine's economic and military models are simplified but draw on real datasets (Maddison historical GDP, SIPRI military expenditure). Specific event probabilities are tuned for replayability over historical accuracy.

Can I play as a minor power?

Yes. Smaller nations have less budget but more flexibility — alliance-shopping is a viable strategy. Some of the strongest scoring runs come from middle-power coalition-building.

How long is a campaign?

60 in-game years = 240 turns ≈ 90–120 minutes of real time. Save and resume across sessions.

Is multiplayer planned?

Asymmetric hot-seat (different powers per session) is in design. Real-time multiplayer is not on the near roadmap.
