Why is biology important in Galactic Civilization IV?

  • The biologies offer several advantages and disadvantages based on the residing planet.


Carbon Based – The chemistry of carbon-based species is based on water and hydrocarbons. To thrive and grow, their population requires food.


Aquatic – Aquatic species live most of their lives in the depths of the oceans. They have to access unique Aquatic Techs, and they can also colonize Oceanic Worlds without penalty.


Silicon Based – Silicon lifeforms are created from rocks and rare minerals. They do not need food, but their growth is slow unless they have access to copious amounts of Promethion.


Synthetic – Synthetic lifeforms do not need food to survive, and they can thrive in a variety of harsh environments where organic lifeforms would perish. When required, they can also fabricate new individuals and grow their population virtually unfettered.


  • Biology also determines the type of planet on which you will embark on your adventure. For example, a race of Aquatic people would be better suited to an oceanic planet.



Galactic Civilizations IV – A Brief overview of traits and what they do

  • Civilization traits grant several strengths and weaknesses.


  • All civilizations have three points to distribute among each trait and the only way you can add more points to any given trait is by taking it away from another one.


The Drengin Empire for example has Intimidating +2, Unlikeable -1, Militant +1, Brutal +1. The extra point in Intimidating is balanced out by taking a point away from Unlikeable.


The following is a list of all the traits, along with their descriptions:
