Galimulator

Galimulator simulates the wars, revolutions, politics, research and various other bizarre events in a randomly generated galaxy. Watch as space empires endure epic struggles for power. Ultimately they will go away, crushed by a stronger race, victims of internal strife, eaten by space monsters, or some other fate. But new ones will take their place. It's the hypercircle of interstellar life in space. Follow the fates of Dynasties and individual people as they rise from low level paper pushers, and rise to become Captains, Ministers or even Emperors. In Emperor mode, you can control your own empire by using your Flagship to boost expansion and defense, build and control your ships, and manage your Spy network. In Sandbox mode, you have full freedom to do pretty much what you want. Make empires degenerate, throw meteors at them, etc. Or you can just observe, like an aquarium, except with interstellar space empires instead of fish.
