Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Galactic Simulator is a clicker game based on the Fermi Paradox and the Great Filter theory. Players can simulate the evolution of celestial bodies and civilizations in the galaxy from an observer's perspective.
As of now, there is no reliable evidence to suggest that extraterrestrials have visited Earth.
— "Where are they?"
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 implements all the components of this formula.
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 defines the following Great Filters (evolutionary stages):
Suitable stellar systems and potentially habitable planets
Organic molecules (e.g., RNA)
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.
Once a planet reaches the civilization stage, it begins to develop its level of civilization, measured by the Kardashev Scale.
Each planet has its own unique appearance and is fitted with real-world physical data.
If you're unfamiliar with the above theoretical background, don't worry—the game isn't complicated. There are only a few key click actions, and it provides detailed explanations and auto-completion options.
Even without any player input, the galaxy will evolve over time on its own.
Tips on in-game camera controls: WASD to move, Q/E to rotate, Z/C to zoom
Casual Mode:The success rate of most in-game events and the Great Filter is set to 50%.
Realistic Mode:More realistic success rates and data to simulate the real world.
Sandbox Mode: No resource use or generation, can advance universe time.
The game supports multiplayer mode. Create a unique galaxy with friends!
Supports leaderboards, letting players worldwide see your unique planet.
Supports screensaver mode for a stunning display of your galaxy—best experienced in full screen!

天然适合天文爱好者,挂机玩法,通过随机搜索捕捉未知行星,观察行星状态,很休闲。建议增加一点点新手,刚开始有一点点蒙。
Honestly speaking, being a galaxy observer is a joy. Watching planets, each so different, slowly evolve and either form life or not, before the Great Filter—it’s fascinating. I once observed for 7 hours, but the highest I got was eukaryotic cells, and in sandbox mode, it only reached intelligent creatures, not yet the tribal stage. I wish that, instead of just observing the universe, I could create a planet in some corner of it, help it overcome the filters, bring asteroids carrying the materials for life, and look forward to Galactic Simulator 2 so I could land on the planet I created 😄

玩法挺简单的,但是很肝,比较吃运气
一直坚信有外星人,毕竟宇宙实在是太大了,可惜我们寿命等不到科技大跃进的时候。
我比较喜欢沙盒模式,不用管资源消耗,纯粹观察恒星系统的形成和文明的兴衰。每颗行星的物理数据都是独立生成的,看着它们在银河系里慢慢变化,有一种独特的沉浸感。
主要的玩法还是看海,ui稍显简陋
感觉很深奥,各种数据看的眼花缭乱,老实说没太玩明白,但是这种游戏形式给我的体验很新奇,而且银河很漂亮!
在经历了长达26小时的间断观测(指删了存档重启),第六次观测中,在我不在家时在Wolf-1444(K)的一颗83的行星上出现了一群智慧生物,但经过千万年的进化后,他们停滞了,停滞在了进入部落时期的临门一脚,之后沉寂了2500万年后,一名叫Tolds的观测者路过顺手帮我重新激活了这个星球上的观测,使他们得以进入部落并顺利进入文明阶段。如今休闲排行榜上的Wolf-1444文明 感谢tolds的协助。谢谢你。 之后刚过两百万年,我的银河系再一次扫描到了太阳系与地球文明。热闹起来了,我的银河
天体物理爱好者福音~很挑人的游戏~
一个大型的宇宙沙盒,观察星河的演化,物种的演变,整体游戏节奏较慢,建议当做一款挂机游戏来体验,银河挺漂亮的
