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.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 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

Enjoy the depth of a 4X game in a fraction of the time! A game of Space Imperia 4X typically lasts one to two hours. The game is played over a series of rounds, with each consisting of three turns of movement, combat, and exploration, plus one turn of researching techs and building ships.

The only goal of the game is to eliminate all rival home worlds! Victory calls for a blended strategy, including resource management, ship construction, technological research, and tactical-level decisions on a map where no two games are the same.


Build up to 17 different combat and civilian ships, each with different stats and purposes.
Dreadnaughts are the most powerful ship available in the game. They take dedicated research and infrastructure to unlock and yield effectively. Once available, however, its combat stats are the best in the game and a fleet of them can decisively end the game. The counter: any ship is vulnerable to Mines — and these massive capital ships are no exception.
Raiders are Cloaked - nimble, first-strike craft that can move through enemy formations and get special bonuses in combat. They require a special technology to be built. A well-timed fleet of Raiders often leads to decisive victory. The counter: Raiders don't work in Nebula, and Destroyers can equip Scanners to negate the cloaking.
Fighters are pure strength in numbers doctrine. Fighters are cheap to build, while Carriers are expensive and are required to move Fighters around the battlefield. Fighters attack earlier in combat, allowing them to first-strike other ships in large numbers. The counter: Scouts can equip Point Defense to shoot earlier than enemy Fighters, negating their advantages.


Research up to 14 different technologies, each with a distinct role. Master the full toolkit to outmaneuver and destroy your rivals.
Ship Size gates which hulls you can build. Bigger hulls take more hits to destroy and carry higher-level technology, but cost more to build and maintain.
Exploration allows Cruisers to equip advanced sensors which can discover adjacent systems without movement. Scout hazards like Black Holes safely, then craft an informed plan to defeat the enemy.
When ships of the same Weapon Class fire, the ships with higher Tactics shoot first, potentially securing kills before the other ship ever acts.


Uncover a galaxy filled with different terrain types, harvestable minerals, and derelict ship wrecks. Balance the risks and rewards of exploring Deep Space while carving a path toward your rivals' home worlds. Colonize newly-found habitable worlds. Not all worlds are the same - when colonizing, Barren Planets need special Terraforming technology, while Alien Planets require military action to clear alien ships.

Build and expand a network of Merchant Ships and Miners to increase credit income and economic production.
Manage your military fleet - decide what ships to build, what techs to equip them with, and how best to defeat the enemy's formations. Deploy your fleets on the battlefield to vie for control of deep space in order to ultimately destroy your enemy's home world. The combat system of Space Imperia 4X is a rewarding mixture of scouting, positioning, attacking, and bluffing - all combat ships are concealed from the enemy until first contact!

Play in over 10 different scenario setups of 2-4 players, with optional rules and various ways to play. Full multiplayer support, including live matches, long-term asynchronous games, as well as online co-op vs AI matches.

So far, I'm impressed with what Breich Games have accomplished here. The game plays just as the original board game, with a few tweaks that are minor at best. It is one of those rare PC/Console games that remains very faithful to the original game. It's also nice to see the very modest requirements for you PC to run the game. In my case this isn't an issue, but several of my friends commented on that. What I like: ** The game plays and feels like the original following the rules faithfully. ** The interface is mostly just fine, I do have a couple of gripes I'll get to though. ** Multiplayer is working well also. The Discord connection is just for Turn notification, but that didn't bother me as I'm on Discord a lot anyway. ** The ease of setting up and playing the game quickly. ** A designer who actually tracks and responds to any issues folks might be having with the game. Any designer who interacts in a good way with his/her customers is a big plus to me, considering some of the lacking support we see with so many games these days. What I don't like: ** Lack of hotseat mode - however this is being worked on, so I don't consider it a long term minus. ** AI instances of strange game decisions and play - this too is being worked on, and it will take some time. ** Lack of solitaire scenarios that were in the original game - yet another thing that the designer is aware of and working to incorporate. ** The AI needs some work, both in exploration and in tactics - it has a tendency to attack piecemeal. Things I'd like to see implemented: ** Of course, the expansion content, but that's coming. ** I do miss the different ship designs for the four initial factions. The color coding works fine, and does make it easier to tell the ship classes apart, so this is a small aesthetics thing. ** Consider increasing the font size of the key binds for the various ship actions. Right now, they are tiny and shown by the button. I missed them for a bit before I realized they were there. ** The bottom of the Firing section of the combat screen has some buttons at the bottom that are cut off, there is no text there. Or well there is, it's just not visible. My negatives are either not that important, or are being worked on by the dev, so overall I do recommend Space Imperia 4X. It's a faithful adaptation of the original board game Space Empires 4X, and it's a fun way to jump right into the game and play a match or two with friends. I'm looking forward to further development of the game.
Fun game and I can't wait for more good things added.
