What is Terra Engine?

Terra Engine is a geopolitical strategy sandbox where you play as a leader (or remain a spectator) in a living world, shaped by a historical timeline and factual data.

Around you, politics, economics, and diplomacy unfold alongside events and disasters, while issues and crises structure international tensions. Other leaders are driven by AI; language models remain optional for a more immersive experience.

Historical data and timeline

Nearly 8,000 entities (countries, people, organizations…), almost 10,000 time series, and around 2,000 historical timeline entries: together they rebuild the world at the chosen date and keep games coherent.

Historical mode

Historical mode controls how the simulator follows real-world trajectories: indicator convergence and major developments according to the chosen fidelity level; when turned off, it opens the door to alternate history and custom scenarios.

Detailed political simulation

Manage different regimes, elections, successions, and power dynamics. Each country has its own evolving political system with institutional capabilities.

Macro-economy

Macro-economic system simulating GDP, unemployment, debt and other indicators evolution. Each country evolves according to its category and economic state, with a configurable historical mode.

Diplomacy and international relations

Develop international relations, influence opinion, and conduct various diplomatic actions between countries and leaders.

Issues and crises

Lasting geopolitical dossiers (nuclear programs, disputed territories, spheres of influence…) feed escalating crises: structured camps, objectives, and actions for embodied leaders and allies. About a dozen contemporary issues tie into the historical timeline; AI agents assess and react to rising tensions.

Interactive event system

Make key decisions through multiple-choice events and conditional triggers that shape history.

Natural disaster simulation

Historical natural disasters: earthquakes, cyclones, volcanoes. Damage per hexagonal cell (devastation, casualties) and visualization of phenomena.

Hybrid AI and autonomous agents

Two-tier AI architecture: standard mode for fast decisions and language-model mode for narrative immersion. Each leader acts autonomously with contextual decisions and reactions to political, diplomatic, and global events.

Intelligent AI tools

Conversational assistant to discover and use the application, and AI Journalist generating interactive news.

Modding and multilingual customization

Extend and evolve the experience: mods, languages, events, properties, and scenarios. Terra Engine is built as a modular platform, already available in French and English.
