Stronger, smarter, faster - v2.8 for Galactic Civilizations III brings major AI improvements

AI for the massive-scale space strategy game now more human-like thanks to v2.8's "supreme commander" system update

For a complete list of changes, see the changelog at the bottom of the post!



What’s New in v2.8:

v2.8 leverages one of the greatest advantages of Galactic Civilizations III: its new, 64-bit, core-neutral game engine. Since most PC gamers have at least 4 CPU cores, we took the opportunity to develop a semi-genetic algorithm based AI that allows the computer to play much more like a human would.

GalCiv III is already known for its good computer opponents. To continue creating new depth of experience for our playerbase, the new asynchronous “supreme commander” AI will observe and send priorities for computer empires, which will feel much more like playing against another human.

We want players to have lots of viable strategic choices. To that end, we have been making lots of balance updates over the past year. v2.8 will help players play as a “tall” empire as well as a “wide” empire by giving them the potential to tilt the balance of the galaxy through smaller empires and well-run nation states.

The final focus of the new update has been in the ongoing drive to make the game more approachable without sacrificing its celebrated depth. A number of new UI elements to streamline gameplay, additional in-game descriptions, and more. Some changes are minor improvements, like moving rarely-used features to a different place, but other changes like defense modifications for ships will make the game even more intuitive and satisfying.

  • Industrial Sector maint reduced from 2 to 1

Hey, famous movie star, here's some metallic ore for you. Please do a USO tour. Because... you know, you'll get some ore!  As the famous saying goes, you will attract more celebrities with flowers than...ore.
  • Fixed shipyard window to always show the military production generated by the sponsors regardless of if there's a ship in the build queue or not
  • Fixed issue in influence system where it was displaying "Foreign ship in your ZOC" alerts for ships owned by allied players

Galactic Civilizations III: Intrigue Expansion Delivers Politics on a Galactic Scale

Now Announcing Galactic Civilizations III: Intrigue!

Establish a reign that starts on a single homeworld and expands across the galaxy.
Billions of citizens. Thousands of light years. One strong leader: you.



Assemble your cabinet of advisors, choose a form of government, and
earn the trust and faith of your people in Intrigue!

KEY FEATURES

Form your own government.
Bet you wish you'd paid more attention in your high school government classes!

Each style of governing has its own advantages and disadvantages and affect the way you'll run your civilization. Your technology, species, and cultural ideology will determine what types of governments are available to choose from. You'll also have the opportunity to appoint a cabinet comprised of your citizens to help customize your civilization and how it will operate. Some forms of government require elections, which means that you'll need to keep your populations happy in order to gain all the benefits and bonuses.


Establish a commonwealth.
Put your colonies on auto-pilot!

As your empire grows, worlds on the outskirts will want to become independent. By granting these worlds a status of commonwealth, they will be converted into an ally with a favorable disposition and will be inclined to implement your requests on the galactic scene. Thanks to the established AI, these civilizations will operate effectively without too much micromanagement or oversight required.


Buy, trade, and sell in the Galactic Market.
There's always a good deal at the Bazaar!

Well, maybe not always, but that’s what they’ll tell you, anyway. Previously, resources could only be obtained by trading with other civilizations, some of which might have been unwilling to make a deal. Now, you'll be able to purchase resources from a galactic market where the prices are determined completely by supply and demand.


New technologies, planetary improvements, weapons, and more!
Newer isn't always better, but in this case...it is.

Awesome new ship modules and devastating weapons, unique planetary improvements, and technologies designed to improve your government are packed in Intrigue. All of these new additions will require galactic resources, which is what makes the Galactic Market so important!


Keep up with current events using the Galactic News Network.
In space, there is no biased reporting - that's because we've hired a robot to handle it!

Check the news to monitor who's allying with who, who's declared war on each other, and many other activities that are going on across the galaxy.


Galactic Civilizations III: Intrigue coming Spring 2018!
