Massive Starbase Update for GalCiv III is now available!

Too many Starbases, not enough time? No problem.

GalCiv III v1.7 Brings Starbase update to solve all your management problems!

We know that many of our fans love playing gigantic-sized maps over sprawling hours of game play. The new Starbase update brings several new features and tools for reducing micromanagement and increasing efficiency for those late-game long hauls. Check out some of the update's highlights:

Queue Upgrades Directly from Shipyards
Constructors are ordered from the Shipyard that can deliver the upgrade in the shortest amount of time and will now automatically travel to the Starbase.

Plan Your Battles...and Your Retreats
The new "Battle Assessment" feature allows you to hover your mouse over an enemy fleet to see an estimation of your fleet's victory against them.

Sort and Group your Ships with Ease
New options make it easier to find the ships you want when you want them. Mark your "favorite" ships so that you can snap right to them in a hurry!

Make Friends, Not Enemies
The update to diplomacy has made it so that your allies are more likely to give you a good deal on trades! Trade value will now scale based on the game's difficulty setting and your relationship with other factions.

Easily Access Starbase Modules and Effects Info
The "Starbase Window" displays more detailed statistics and will aid you in managing the Starbase and the rest of your empire.

Maximize a Colony's Potential
The new "Planetary Alert System" will warn you when your influence, population, or approval are holding your colony back.

...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.

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.

CORE FEATURES:

  • Never the same game twice: Play in the ultimate sandbox where each game has a unique map, worlds, and challenges to face -- all on a massive scale. Play against 16 to 100 opponents.

  • New Battle System: Assign your ships specific roles to play in combat. You can now view fleet battles in a cinematic style to see your designs in action.
  • New Colony Manager: The location of a planetary improvement now matters. Adjacency bonuses and planetary resources make a major impact on what a planet is strong (or weak) at accomplishing.

Altough the DLCs are really a shame from initial Stardock spirit (independant gaming) and are really light for their price, this is a solid 4X that can grapple you for hours, in the spirit of the old gal civs.

I've been waiting to play this game for at least two years. The Galactic Civilizations franchise is simply playable for me. Whenever I play the game it reminds me of a seriously complex and imaginative game of chess....in the middle of the Universe. Love 4X games in general and Galactic Civilizations is simply one of the best. Being turned based, Galactic Civilizations gives a lot of meat to the methodical thinker. You take your time to plot your plans for galactic conquest. Your mind is thinking 20 or more turns ahead in many instances. I've never left a review for a game before but am compelled to leave this review.

To premise my thoughts on GC3, you'll never truly experience the greatness of this game unless you've played previous versions. Even starting with GC2 and all of the expansion packs. I say this because the original game is still so easy to play once you grasp the UI.

Galactic Civilizations III offers a really great twist on an already incredible concept. The new game seems quite more involved than the previous game. The toggle between tasks on each turn, for instance, is extremely intuitive to game play compared to previous versions. It allows for one to consider each move carefully and individually rather than collectively, as before. For example, the new Galactic Civilizations offers a nice change to mining. It actually combines the star base and mining ships into one. But the mining is so much more important this time. You have to collect resources to build advanced options in colony building and ships too. Though I completely love GC2, the miners were mostly on auto pilot the entire game. You could build more and faster ships to complete their tasks, but one never really was able to process the true value of mining ships in previous versions. There are other examples along these lines.

The UI seems to have cut the "fat" off of its predecessor. It runs more lean. But there are other things to focus on. The important things. And in that sense, the developers have made it easier to manage.

However, there is one huge complaint I have. Ship building. In GC2, ship building was like putting together a Lego space ship, on a very minimal scale, but none the less incredibly cool. The new game doesn't seem to have those capabilities. And if it does, I haven't figured it out in 20 hours of game play.

In summary, if you are a Galactic Civilizations fan, this is a no brainer. You'll love it. It's different but the pieces are the same. If you have never played previous versions, no worries. You'll need to take your time to get the concepts down. As long as you are fairly patient and love long term strategy this game is incredible.

Like I said, I've been waiting for some time to play this game. I generally give a game at least six months to patch and fix the bugs before I buy it. I was content with GC2 and a few others waiting to check out GC3. Can't say it enough, it is great game but it builds on previous concepts. Not to say that one couldn't pick this game up without previous knowledge of the series, but it will require you to patiently develop an understanding of how intricate the game can get.

Thanks to the folks at Stardock for sticking this game out. They took something incredibly great and made it better. And that is something that we rarely get in the video franchise world.

Fun but frustrating. Its very easy to put hours and hours into a game then realize you are screwed and cant win. Actually MOST of my games have ended up that way. Upgrading starbase defences is marginal at best. Hig end defenses are resource intensive and not effective. The AI gets odd perks that I really dont think they need. Its a games that i have tried very hard to enjoy and havent really been able to yet.

Have played for about 6 hours now and I am sorry to say that this 4X game is not anything decent in my eyes. I have played Sins of a Solar empire and Master of Orion and they easily take this to the house in playability and entertainment.

Waste of money overall and still having trouble getting it back as it takes more than the 2 hours to even get a feel for this game and Steam is being stingy.

As a big fan of Galactic Civilizations 2, I came into GalCiv3 with the understanding that it was going to be very similar. That is fine, in this case, because similar to "good" is likely to be "good".

The biggest issue with GalCiv3 is that some of the information is simply missing. It could very well be that it is available and I don't know how to access it, but if so, even that is a problem.

I enjoy the game, and happily play it while at the same time hoping for a more complete version.

I do seriously love this game but the music is the most annoying thing ever. The soundtrack sounds great, but in the game a 15 second clip of what sounds like a cheap rip off of the theme from Stargate SG-1 is essentially repeated for hours and hours and hours.

While I miss the lovely battle scenes of the second game, Galagtic Civ III definitely ramped up the gameplay with new ship modules, more stuff to place into a custom race, and the United Planets aspect of things. I have nothing to say on the multiplayer, though. Haven't tried it.

Pro's : Very good gameplay, rewarding ship designs, deep and interesting tech tree, solid graphics, decent strategic layout, grand scale.

Cons : End game gets repetitive, major ship hull design changes can get annoying and its hard to make it just right, major slowness late game on huge and above maps.

Conclusion : Pros certainly outweigh the cons, I have been enjoying this game and despite being a little bit shallow on the end game, it keeps me coming back :)

In and of itself, I would narrowly consider this a good game.

However, I write to note that when compared with Gal Civ II, which I played extensively, there seems to be little more in GCIII than an updated UI and cleaner graphics. One must buy a dlc to unlock 2 of the major races that were originally in II. I followed the emails and other updates during development, and also participated in the beta, and I feel that GCIII is more of a cash cow than anything else. There was a ship designer in GCII; they emphasized that it would be improved in III before release, but it is almost identical to that of GCII.

This game is worth $40 only if they gave you all the dlc; buy it on sale, or from a cdkey site for a discount. Otherwise, enjoy GCII which feels more realistic and balanced in terms of AI behavior. It's amazing how they can make $50 of dlc for a $40 dollar update of GCII.

I leave with this: is it fun? Yes. Is it more fun than GCII? Not really. If you enjoy masochistically having your wallet ransacked, this is your opportunity. I have liked Stardock in the past, especially with Sins of a Solar Empire, among other games. They, unfortunately, now resemble EA or Activision.

Turn based space strategy game that has good quality graphics for the different factions involved. The custom designer for your own ship models could use some better tool aids and be more user friendly. I enjoy the games and have tried out the campaign but the AI for your opposing factions seem to be overwhelming even on the beginner settings as very quickly one faction had control of 75 percent of the map.

It is a fun game. So many technologies to resarch, ships to build, planets to colonize, and enemies to fight. It`s difficult but after a while you get the hang of things and build a unbeatable space empire. Or don`t, because you can win buy diplomacy (wuss), research (nerd), or combat (now we`re talking).


9/10 would play again.


Oh yeah plus you can get Halo or Warhammer 40k mods.


Enjoy.

AI seems to very very badly broken. I played GC2 and the AI was far better. Not sure what is wrong but some of the things I have seen are civilazation declaring war when they are not even in range to reach me. AI Power go FAR past anything I can get in a resonable amount of time with follow a very nerrow play style (building lots of warships) which ruins the idea of playing deplomatically and just building colonies.

I loved GC2 so I hope this game can get back to that at some point.

The galactic civ games as a whole are amazing. That said, this game falls short of the previous titles in the series by a wide margin. Just go buy galactic civs 2 instead. It is better on several levels and you can get it a lot cheaper. Unless the only thing you care about is visuals there is no reason to buy this title over the last one.
