- Major Update: The Government Office System — Officials, Cultural Titles, and Local Governance - 7 August 2026
This August 6, 2026 update introduces the complete Government Office System: every state appoints a full roster of officials (by AI or by hand) whose competence directly affects the treasury, provincial output, rebellions, and battlefield command. Official titles change dynamically with culture and government form, backed by a full title editor and map-wide default titles. Also included: streaming-loading optimization for legacy saves. The office system at a glance: States are no longer run by the ruler alone: three tiers and six offices have been added. Central offices (one per state): Chief Administrator, Treasurer, and Marshal. Local offices: the District Governor (governs a district) and the Governor (governs a single province). Wartime office: the War Commander, appointed per war and automatically discharged when it ends. Every office is held by a real character with skills and a f…

- New War System V2: Casus Belli, Peace Settlements, and Capital Fall Crises - 17 July 2026
This July 17, 2026 update brings the reworked War System V2: AI declarations now come with explicit casus belli and war goals, wars are pushed toward the negotiating table by war exhaustion and distress, peace settlements are enforced based on the outcome, and new mechanics arrive: capital fall crises, forced conversion wars, and cultural unification wars. How to switch between V1 and V2: Newly generated worlds use War System V2 by default. Existing saves keep their original war system: old saves still load as V1 and show a notice on load. They are never switched automatically. The switch is in Map Editor → Global Commands → AI Global Configuration: War System V2 (This Save): switches the war system of the current save. Confirming will force-end all ongoing wars, and the choice is stored with this save. War System V2 (New Games): sets the default war system for newly generated worlds. I…
