Diplomacy and Alliances
Agreements, access, trade, sanctions, peace, and collective defense.
diplomacy_and_alliancesContact before certainty
Fog and intelligence levels limit what you know about another civilization. Establish contact, inspect what is public, then choose cooperation, neutrality, rivalry, or war.
Enforceable agreements
Open borders, military access, non-aggression, defensive pacts, embargoes, recurring exchange, research agreements, peace treaties, and the legacy Frontier Pact have server-enforced terms and durations.
Alliances
Alliances have membership limits, invitations, minimum commitment, departure rules, and rejoin cooldowns. Defensive pacts can let partners respond during an aggressor's mobilization period.
Global politics
Late-game projects add congress delegations, resolutions, sanctions, shared research, emergency responses, peacekeeping, and collective defense. MMO votes are designed to stay open long enough for mobile players in different time zones.
