Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Discounts
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.
Reviews, worldwide (the counter carries no country): 0.43/day in the week to Sep 8 → 0.86/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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
Add-ons
Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.
Sums Steam only; Xbox, Epic publish no volume signal, so the true total is higher by an unknown amount.
Updates
Build ids and update times come straight from Steam's PICS — the same source SteamDB reads. Patch history grows as we record new builds.

おもしろいと思う。宇宙版HEX(席)の取り合い。 宇宙版CIVilizationの典型的成功例。(って、これしかないじゃん?) シンプルで昔ウラシマルってゲームがあったが、HEXの部分より それにとてもよく似ている。ゲーム的システムを感じた(?????) 細かいところは今のところ、 後継作の4よりもおもしろいかなぁと思う。 やってみればわかります???
Kb. az 1.82 verzióig (Altarian Prophecy) szerettem. Utána érkező frissítések szerintem rossz irányba vitték a játékot. Azért még így is szeretem.
Komplexní 4X strategie s bohatými možnostmi kolonizace a diplomacie. Nabízí hluboký zážitek a variabilní hratelnost, ale pomalejší tempo a složitější rozhraní nemusí sednout každému. Solidní volba pro fanoušky žánru.

Nice game.
Ah yes, Galactic Civilization III. The crown jewel of space turn based strategy. A game with so much stuff that people can fail to realize just how easy this game really is. The thing about this game is that the combat makes no sense and unless you spend hours figuring out how fleet composition works then you never really feel like you know how to win. GameSpot gives this game a 10/10 on realistic Space combat. That being said, this game allows you to be in debt and charge your citizens a 0% tax rate. C`C~P gives this game a 10/10 for realistic communism- I mean economy. In general, mercenaries are the way to win the game, so once you have access to them, forget ship upgrades and building your own military and just buy yourself one. But really, who wanted a several day lasting game with epic politics and total space opera immersion when you can just buy mercenaries and win in a few hours?
Fun watching the Ai play against Ai =]
Great game to kill some time
i can make this game run slow and i like that as i'm old and slow too
Recommended but note that Gal Civ 4 is better in every way. In addition to a shiny upgraded UI, Gal Civ 4 is a more immersive game experience with better mechanics overall.
