About Galactic Simulator2: Stargate

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 civilizationThe 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.

A master class in bad UI design overlaying a fundamentally uninteresting gameplay experience. Here is every turn: Click scan, click current star, click explore, click every planet once, hover over stargate spots and click the one with the highest efficiency, click button to exit explore mode (no hotkey), click same star again, click stargate, click target star to connect stargate to that star, click target star, click jump, click end turn. Sometimes you might also have to click 'exchange resources' and then buy new probes. That's it.

maybe worth it on sale, but absolutely not worth 6$, I agree with what the other negative review says, I can live with poor UI but the fundamental gameplay loop is just kinda boring, and resource interest makes it so you barely even have to play the game at a certain point.

I don't know what I am doing, just clicking buttons "available" that's pretty much it. There isn't really any "game play" just buttons available per "turn". Very uninteresting. There is no tutorial, because their isn't really anything to do.

After you Max out your ship, and have a lot of resources the gameplay runs out of steam. Also I feel like I would have enjoyed this a lot more if the galaxy map and the system map remained front-and-centre during gameplay. The other elements could slide in from left/right/bottom to cover a much smaller portion of the screen. The planets look good, and I appreciate the data list that tells you about their physical properties and environment. I enjoyed scanning and linking stargates, but I think the stargate linking interface should be an overlay on the galactic map.
