Galactic Simulator 2: Stargate is a roguelite simulation game inspired by the Fermi Paradox and the Great Filter. Pilot your ship, gather resources, build stargates, and discover other civilizations as you explore an ever-evolving galaxy.

Fermi Paradox

As of now, there is no reliable evidence to suggest that extraterrestrials have visited Earth.

— "Where are they?"

Drake equation

N = R* × Fp × Ne × Fl × Fi × Fc × L

    N：The number of detectable extraterrestrial civilizations in the galaxy

    R*：The rate of formation of stars in the galaxy

    Fp：The fraction of those stars with planetary systems

    Ne：The number of planets, per solar system, with an environment suitable for organic life

    Fl：The fraction of those suitable planets whereon organic life appears

    Fi：The fraction of life-bearing planets whereon intelligent life appears

    Fc：The probability of a civilization emitting detectable signals

    L：The lifespan of a civilization

The Drake Equation helps us understand the probability of extraterrestrial civilizations existing. Galactic Simulator 2: Stargate implements all the components of this formula.

The Great Filter

The Great Filter is the idea that, in the development of life from the earliest stages of abiogenesis to reaching the highest levels of development on the Kardashev scale, there is a barrier to development that makes detectable extraterrestrial life exceedingly rare. According to the theory, Galactic Simulator 2: Stargate defines the following Great Filters (evolutionary stages):

• Suitable stellar systems and potentially habitable planets

• Organic molecules

• Prokaryotic cells

• Eukaryotic cells

• Multicellular Organism

• Intelligent Organism

• Tribal Stage

• Civilizational stage

Civilizations have a probability of failing at various stages of the Great Filter.

Explore the Galaxy

• Each planet has its own unique appearance and is fitted with real-world physical data.

• Build stargates to connect stars, from your homeworld to the vast galaxy.

• Supports leaderboards, letting players worldwide discover your unique planet.
