Galactic Simulator

Galactic Simulator is a clicker game based on the Fermi Paradox and the Great Filter theory. From an observer’s perspective, you simulate the evolution of celestial bodies and civilizations across a galaxy. The galaxy also continues to evolve over time without player input.

The Fermi Paradox

The game explores the question of why there is no reliable evidence that extraterrestrials have visited Earth. It implements every component of the Drake equation, which estimates the number of detectable extraterrestrial civilizations in the galaxy:

• The rate at which stars form
• The fraction of stars with planetary systems
• The number of planets per system with environments suitable for organic life
• The fraction of suitable planets where organic life appears
• The fraction of life-bearing planets where intelligent life appears
• The probability that a civilization emits detectable signals
• The lifespan of a civilization

Evolutionary stages

The Great Filter theory proposes that barriers during the development of life make detectable extraterrestrial life exceedingly rare. In Galactic Simulator, civilizations can fail at different stages, from the formation of potentially habitable worlds to the development of civilization:

• Suitable stellar systems and potentially habitable planets
• Organic molecules, such as RNA
• Prokaryotic cells
• Eukaryotic cells
• Multicellular organisms
• Intelligent organisms
• Tribal stage
• Civilizational stage

Once a planet reaches the civilizational stage, its civilization develops according to the Kardashev Scale.

Planets and play

Each planet has a distinct appearance and is fitted with real-world physical data. The game uses a few key click actions and provides detailed explanations and auto-completion options.

Game modes

• Casual Mode: The success rate for most in-game events and Great Filter stages is set to 50%.
• Realistic Mode: Uses success rates and data intended to simulate the real world more realistically.
• Sandbox Mode: Has no resource use or generation and allows you to advance universe time.

Multiplayer and other features

The game supports multiplayer, so you can create a galaxy with friends. It also includes leaderboards where players worldwide can see your planet, along with a screensaver mode that displays your galaxy.
