The elf is back and more

The lead developer of Galactic Civilizations I and II has returned after a multi-year maternity leave. She's rejoined the team and you will soon begin to see her contributions in game.

It's an exciting time to be a GalCiv III player. We've staffed up over the Summer and have been working on the next big expansion along with what will eventually be called v1.9 of GalCiv III.

There's no particular theme for v1.9 other than trying to make the galaxy a bit more organic. Smarter AI, better diplomacy, tweaks to balance and performance.

On the expansion side, well...that's a different story. The next expansion, due out early next year, is designed to revisit pretty much everything in the game, particularly in the area of economics and foreign policy and planetary invasions.

We've been having a blast talking to GalCiv fans. There's a wish list thread that we mine heavily for ideas. We usually don't comment but we regularly will print out forum comments from or from the Steam forum and discuss them.

Stay tuned!

About This Game

The human race has finally mastered faster-than-light travel opening up the stars for exploration and colonization. As the leader of the newly formed Terran Alliance, you will guide humanity's expansion into becoming a space-based civilization. Soon, you will discover that we are not alone. Alien civilizations with their own histories and motivations are expanding as well. Research new technology, design starships, negotiate trade and treaties, wage wars, colonize new worlds, construct starbases in the largest 4X strategy game ever made. And when you've finished that, play again as one of the many included alien civilizations each with its own history, technology tree, ship components and more.


Each new game offers an array of options as you set it up - choose your map size, abundance of planets and resources, frequency of events, and more for a unique play experience every time. Galactic Civilizations III also removes linear victory conditions and offers you multiple objectives that you can choose to pursue in order to win, such as military conquest, cultural domination, technological ascension, or political alliances. The new multiplayer capabilities also allow you to expand your challenges and fights beyond an AI in order to face off against fellow players. All of this, topped with a rich and in-depth custom ship designer ensure an immersive and exciting experience as you decide how to rule your galaxy.

I feel burnt here...I love Gal Civ, I've played since the 1st one and loved the 2nd. So I was excited when I heard they were working on the 3rd installment. I quickly pre-ordered and played some in Beta. On release I played, but it felt incomplete, then DLC's start coming after I bought the game now I need to shell out an addition $50 for the game to be what it should of been. No game is worth $100... Stardock you have lost my respect...

I didn't pay for a DLC simulator. This is still buggy, performs poorly (especially shocking coming from this company) and the content is just not there. They remove features that were present in GC1 and 2 and sell it back as DLC. What the ♥♥♥♥ happened to this series? I loved GalCiv2 and played the ever-loving ♥♥♥♥ out of it, but this I can barely stand.

The combat is a lot better and the super silly writing is mostly absent, which I like. Other than that, this feels like its just here to keep piling DLC on.

Looks like Stardock has done some hiring and are active with the community in fixing things. Good sign, let's see where it leads.

It is one of the most wonderfull games and game franchises I know.
The pace may feel a bit monotonouse , but it is actually perfect match to what things go like in real world.
I have always loved John Brinn s Uplift novels and this reminds me of them , I wish the next version had some of the elements of his universe .
Like Uplifting alien spevies to sentient state , finding more diverce ruins and space artifacts with more varied qualities and aincient knowledge repositories , that are hard to get to ,but sometimes set you on utterly different path of development.

Very Slow if played right. The regular game is fun but with lots of weird aspects. For example I noticed early that you can run a fairly substial deficit most of the game. I ignored cash lost hundreds per turn, for about 100 turns I was alwase 10 turns from going broke but I just found enough to keep me going. Setting up a good starbase network around your planets takes forever and gives you such a huge economic advantage, but slows your game to a crawl. I easily spent half my game setting up starbases. The campain is super easy and its more of a tutorial than anything else, just fly towards the end and win.

Ai are the dumbest ai across any game.

They have no sence of technology, no idea how to trade with any reseanable ability except to keep the player constantly busy as he/she out-trades all ai with ease.. Trade offers are always a laugh.

Ai will always build predicable bases with no attempt to defend it - ever.

Zero tactics building up to combat and battles are just a movie.. Yawn.

anomalies spoil the game as only the player uses them correctly, every time.. Example :- the AI are allergic to shipyards.

I have tried to play many times where I've set up the game to purposefully hinder me and I still find the ai are too dumb to be a challenge to me, let alone a 5 yr old.

I've been buying all dlc as released in hopes to make it better but no, its just a time killer with no end game elation.

As a fan of the previous games, I enjoy this game a lot. While I won't say its strictly superior to the previos version, it does have some nice new features and a lot of DLC content available for it.

If you've loved GalCiv 1 and 2, you'll love this even more - and if you never played those, but have been looking for a 4x game in space, the newest GalCiv will have your need for 4x sated.

With the 64-bit engine your yuuuuuge galaxy can be humongous. Frequent updates, customization options, the ship designer and expansions/DLC ensures you'll be able to make space great again.

Also features a great "spacey" soundtrack.

I love strategy games and Galactic Civilizations 3 is briliant. I love the exporation with the thrill of finding a new planet. Each choice has a real impact on every game making for near infinate replayability. The planet development and building adjacentcy bonuses make every planet unique. Last the ship design while very easy to do is very rewarding in not only asthetic but how it affects gmaplay in major ways. This game makes me feel as if each game is new and exciting as the sheer amount of costomization involved and the planet generation is never the same game to game!

I loved GalCiv2, and I was very excited for this new game (I was a junior founder, I bought in early). Now I am not so excited. I think it is the best new 4X game space game out there, but it frequently fails to live up to its predecessor, and it certainly doesn't feel like it has benefitted sufficiently from nearly a decade of advancement in gaming. This game has great potential, but after waiting a year for it to be realized, I'm beginning to lose hope. If you like space 4X, sci fi, or galciv2, you might try picking this up on sale, just to see if you like it. Don't get too excited, though.

Here's a short breakdown:

Pro: Multiplayer (finally!)
Con: Multiplayer doesn't really work well
Con: How long will the game keep making money and therefore being supported with limited multiplayer?

Pro: AI is what the developer prides itself on
Con: The AI is not very good
Con: Worse, there are obvious exploits
Con: Someone with a knowledge of basic probability needs to go over the game mechanics... there are some weird bits*

Pro: Huge maps and the ability to play over 100 opponents
Con: Only comes with a dozen factions. The rest are crowd-sourced on Steam, and they are generally lackluster.
Con: Only a slow trickle of "offical," complete new factions from the developer, and they seem to actively avoid adding them
Con: The first race they added in DLC is a species of super-aggressive squirrels that started in GC2 as a joke... seriously

Pro: Fine graphics
Con: The movies use proprietary software, so it is much harder to add new ones
Con: Certain things, like lights for ships and faction map colors, are limited and difficult to mod
Con: Clumsy interface

Pro: Lots of DLC support
Con: The DLC is mostly weak and disappointing
Con: The first expansion was similarly weak

Pro: Delightful ship designer
Con: You can only design ships in-game, no independent shipyard
Con: The designer is terribly organized and harder to use than the GC2 version

Pro: There is customer support
Con: You can't just record a bug, you have to send them a video showing them something they could reproduce on their own computer
Con: And they will close a ticket if you don't get back to them very quickly (they are not so prompt themselves)

Pro: Extensive modding support
Con: You can't upload mods to Steam
Con: Some programming shortcuts make "obvious" mods difficult (not unique to this game, I'm sure)**

Pro: Design as many factions as you want, supports multiple custom civilizations
Con: But they are in an uneditable form outside of the game***
Con: There is no interface for editing factions, you have to start a game
Con: Large numbers of factions become unmanagable in an administrative sense: how do you find the one you are looking for with no search and no rational order to the listing?
Con: Odd choices in programming colors limits the customizability of ships, interfaces, etc.
Con: Game still doesn't include all of the factions remaining at the end of GC2 (Drath, Korath)

Pro: Some "interesting" new game concepts, like tourism (yawn) and mercenaries (yawn)
Con: Lacks, or nerfs, many of the features of GalCIv2, including spies (coming), asteroid miners (nerfed), terror stars (maybe someday)
Con: Major features that came with the basic GC2, like politics and political parties, are gone. United Planets seems to be significantly nerfed.

Pro: The developer is very good about updates
Pro: The developer often throws new content into updates
Pro: The developer is pretty clever
Con: There seem to be a lot of glitches/ "unadvertised features" that still haven't been resolved despite extensive documentation

* e.g., Class 8 and 11 planets are more likely to occur than an either 7,9, 10, or 12, and random planets cannot be class 17!
** Aquatic ability is hard-wired, adding new strategic icons...
** You can't get the text back out to, say, spellcheck, the the text boxes are too small, the formatting changes unexpectedly, the typing interface is glitchy, and you can't give custom factions everything a built-in faction can (mostly for Steam compatibility)

Overall this is a great game, but I really just can't accept the business decisions of Stardock. It is a shame that they do support german language in the game but only translate the first 2 DLCs into German. All other DLCs and even the expansion pack doesn't support German language. But French and Russian? Are you guys kidding me? I wasn't aware of that crap but obviously they do it with all their games. Almost racist for me.

I wrote this review in english to have get the most out of it, everyone should see this. You guys want to tell me that it's easier to translate into Russian than into German?

This was the last game I bought from Stardock. I am very disappointed with that kind of business model.

I encounted two bugs that practically broke the game with in the first 30 minutes of real gameplay. Don't bother getting this until the devs really get to some bug fixing. Otherwise, it's just a disappointment trying to work around every oversight, especially for a former fan of the series.

I love this game. I like playing some games solo and this one in my opinion has a great solo experience. If you like hard games set it that way if you like just having fun there's a setting for that as well. Too me it's the equivalant of Civilization only in outer space. It's also well worth the $39.99 price tag. I've been a gamer for over a two decades and Galactic Civilazation has become on of my all time favorites.

As always with Stardock, I was amazed with idea. Content designers are genious. Resourses, technologies, art, idea - all amazing, well thought, in all details.

But I can't play it. It is literally full of bugs, I had to different grave bugs during playing tutorial! First, 'turn button' turned into 'wait' without any reason, so everything worked but there is absolutely no way to end turn. As I am developer, I knew that to do - saved game and loaded it back. Next i saw my fleet disappeared. And game crashed next turn. Gave up.

Don't know what to say. You got 10 for everything except implementation. Interesting that I had exactly same feeling about Distant Worlds.

Guys, could you do something with you developers team? Hire new one, writing in C++? Send them to courses about testing the software? Change the lead? Sad to see such implementation of good ideas.
