Changelog: Updates, Evolution and New Features

Features

• Message system reworked into events: each event is linked to the entities involved, accessible from their panel, and viewable in a global dashboard with an « important » filter and search by entity or period.
• Event texts can now mention simulation entities, displayed as links to their detail pages.
• AI can now handle the full project lifecycle (create, join, leave, pause, resume, cancel) and resolve interactive simulation events on its own.
• AI decision engine debug tool: for each entity, view of considered decisions, their analysis and alternatives ranked by score.
• Enriched action selection interface: context visualization, initiator role selection, and ability to directly target a country as a citizen.

Improvements

• Time progression is now calculated at the end of each day, after all ticks and AI actions have been processed.
• Action type refactoring: cases are now explicit (citizen → leader, leader → country, leader → leader, etc.), paving the way for citizen-side actions and direct country targeting.
• AI agent robustness improvements and various bug fixes.

Features

• Hybrid AI system: leaders can now be controlled either by a standard mode or by a language-model-based mode, depending on the desired level of immersion.
• New shared Utility System: legacy decision trees are replaced by a system that computes a score for each possible action by combining multiple criteria (political context, risks, institutional opportunities, etc.).
• The standard AI mode uses this Utility System to analyze a large number of possible actions and deterministically select those with the best scores, suited to long historical simulations.
• The language-model mode reuses the Utility System results: it focuses on the most relevant actions and turns them into decisions and explanations in natural language.
• Conversational assistant: guides user in discovering and using the application, remains available anywhere in the interface, and can assist during gameplay thanks to full access to simulation data.
• New AI agent system: the agentic system manages task execution and shows task status in the interface.
• The AI Journalist uses simulation events to produce articles and summaries presented as an in-game newspaper.

Improvements

• Glassmorphism interface: dialogs and popovers adopt a modern effect for better readability and a more elegant appearance.
• Political system display: information on political systems, leader successions, and elections is now clearer and accessible via tooltips or character roles.
• Globe label visibility: improved label readability with dynamic management of distance and altitude.
• Relations system between leaders: display and automatic analysis of family links, political relations, and opinions for immediate understanding of power dynamics.
• Added a concept system explaining the main simulation mechanisms, displayed as contextual help in the interface and reused by AI agents to better understand how the world works.

• Leaders now have influence (personal attribute affecting diplomatic interactions and election chances).

Improvements

• It is now possible to choose the default role for leaders with multiple functions; the most populous country is now selected by default.
