Civilization Simulator

4000 BC. Six thrones. One continent. An unwritten history.

Choose your leader — Trajan, Cleopatra, Gilgamesh, Qin Shi Huang, Gandhi, or Mansa Musa — each with their own unique strengths, units, and road to power. The five you don't pick will be carving up the same continent, barbarians burn what is unguarded, and an unexplored New World waits across the western ocean.

  • 🗺️ A living hex world — cities rise on the map, borders spread, armies march tile by tile at your command, in plain words.
  • 🏛️ Five living rivals with real agendas — swear brotherhood with Gilgamesh, out-shop Mansa Musa, out-build Qin Shi Huang, and never, ever push Gandhi too far. Every leader remembers.
  • 🔬 Eras and technologies — from Bronze Working to Navigation to the Industrial age; the world changes shape as science compounds.
  • ⚔️ Four roads to victory — Science, Culture, Conquest, or Diplomacy. And several roads to ruin: revolution, a fallen capital, a world coalition.

Six legends. One will write history. Your move.
