Simulation Genres

Five Genres.
One Engine.

From nation-building to personal economies — every genre runs on the same living simulation core. See how it actually works, live.

Simulation Architecture

Five Genres.
One Living World.

Millenia does not simulate one domain in isolation. Five simulation genres operate simultaneously, each influencing the others in real time. A political decision affects the economy. An economic shift destabilises a nation. A business collapse triggers a population movement. Everything is connected.

GEN_01
Life Simulation
Individual agents — player or AI — live, work, migrate, and form relationships. Population dynamics emerge organically from systemic pressure.
GEN_02
Economics
A localised market system with real supply constraints, labour dynamics, price discovery, and trade flows — no artificial resource sinks.
GEN_03
Politics
Governance structures form, fracture, and reform. Players and AI agents compete for political influence, stability, and sovereignty.
GEN_04
Nation Building
Territories are claimed, governed, and contested. Infrastructure, military capacity, and diplomatic relations all emerge from player and AI decisions.
GEN_05
Business
Corporate entities operate within the simulation — raising capital, hiring labour, competing for market share, and influencing political outcomes.
Architectural principle: No genre operates in isolation. Every systemic event — a factory expansion, an election, a trade collapse — propagates across all five layers simultaneously. The world is one interconnected machine, not five separate games.
The Engine

AI and Players.
Designed to Be Indistinguishable.

// 01
Generative AI as World Citizens
Autonomous AI agents don't manage the game — they participate in it. They run businesses, hold political office, migrate between regions, and respond to systemic conditions just as a human player would. There is no separation between "NPC" and "player" at the world level.
// 02
Blockchain as the Ground Truth
Every asset, territorial claim, contract, and economic transaction is recorded on an immutable ledger. There is no central authority that can override reality. The world state is verifiable, permanent, and sovereign.
// 03
No Content. Only Consequence.
There are no quests, no storylines, no seasonal events authored by developers. Every piece of history in the world is generated by the decisions made within it. The simulation produces its own content, continuously and irreversibly.
