About Dominus Galaxia: KS Edition

Dominus Galaxia is a 4X space strategy game with a focus on amplifying strategic decisions and minimising non-strategic busywork.

This is a fully featured, un-redacted beta release of the game, representing over four years of work, playable from start to finish.

Dominus Galaxia features:
  • Streamlined, slider-based colony management and fleet movement. No build queues to micromanage.
  • Turn-based, hex-based tactical combat, Including turn costs, powerful special devices, and various terrain types.
  • Various types of strategic terrain including impassable nebula, slow nebula, sensor blocking nebula, (optional) starlanes, wormholes, and (optional) transient wormholes.
  • Great gameplay customisability including different expansion modes (build colony ships, build starports or just send colonists directly), optional starlanes, research modes, etc. that alter the feel of the game and add replayability.
  • Choice between static and adaptive AIs, where AI production bonuses can be set independently of skill level. (you can play against smart AIs that have less production than you, dumb ones that have more, and anything in-between).
  • Hotseat multiplayer.
  • Deathmatch and Team Deathmatch game modes — for those who prefer a pure war-game over one with diplomacy.
  • An infinite, semi-random tech tree divided into six fields which can be researched concurrently.
  • In-depth ship design, including an (optional) Diablo-esque crafting component.
  • Tactical combat supporting more than two belligerents.
  • Background combat events use the same logic as player involved battles, not an imprecise approximation.
  • Battles can be auto-resolved at any time. It's possible to manually begin a battle, and after a number of turns instantly resolve the remainder.
  • Planetary bombardment and invasion.
  • Interesting diplomacy, including a tech trading system that has been designed to be less exploitable, and a unique relationship system wherein high relationship helps to maximise trade revenue, while low relationship makes spying more difficult.
  • An intelligence system, allowing you to close-in on how powerful your opponents are across various categories through exploration and spying.
  • Strong modding capabilities. Even many of the game mechanics can be adjusted from text files!

Dead but maybe more development?

An honest attempt to recover the feel of Master of Orion 2. There is even a stylistic similarity to the video cuts : -) There are new aspects to it too -- a mild research tree randomisation, ship design is done in an interesting way, a QoL attempt at reducing repetitive actions into more strategic decisions. I'm sure I missed some..

Loads of fun if you liked early 4X games.

It's pretty fun as it is and can only get better(usually) if it gets finished.
Not recommended May 19, 2026
I first started playing the game several years ago, but stopped because it was impossible - the AI simply had too many resources compared to me. I started again recently because I thought its updates my have made it better. I started with the tutorial, but even though I have a MUCH better computer now, it was lagging in the tutorial! Not serious lag, but there's no way I'm playing a game that lags when only 1 planet and a handful of ships are involved.

Feel is very much like the old Masters of Orion 1 and 2. Took a few games to be able to stand up to the computer player (for me anyhow) Key of course is start as many colonies as you can while they are neutral and develop like mad then make warships that have the most weapons while having a high DR (defensive shield). Then make a bunch of them and go to war. Use chokepoints as much as possible. Play in teams with other AI players and you can see how they develop. Wish you could trade technologies with your allies! Anyhow I put quite a few hours in a few weeks and had a lot of fun. I did not find any bugs. This has been in development for a long time, and I hope it is still in progress.

Games like Undertale that remember what you did

Undertale's own listing calls it the RPG where you don't have to destroy anyone. Games like Undertale that keep that idea: permanent choices, fights you can talk past, worlds that notice.

Most games like Slay the Spire copy the cards and lose the map. These keep the risky-or-safe choice, from a three-floor train to a deck made of poker hands.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
