Civics now behave very much like a second technology tree, with each new civic gradually unlocked by accumulated Culture. Each Civic unlocks one or more items, including policies, district or building types, wonders, and government types. Each government type has a varying number of color-coded slots for policies, and you can mix and match which policies to place in which slot. The starting "Chiefdom" government type has one military slot and one economic slot; later government types have more and different slot types. There are four policy slot types: Military, Economic, Diplomatic, and Wildcard (which is a policy type, in addition to a slot type).

"There were always a lot of things in the tech tree like 'chivalry' that weren't really a technology." - Ed Beach

The "Eureka" objective system that applies to research also applies to Civics (though they are called "Inspirations"); completing these objectives will add huge culture credits toward earning that particular civic.

Civics are divided into the same eras as Technologies are, and you can advance to the next era via Civics instead of technologies.

Tree Analysis

There are hidden bonuses for each Civic that are not listed in the tree view. I will list these in the "Other" column as I find them. The research costs here are based on Quick game speed, but should be viewed with suspicion and as a relative measure only.

All government and social policy changes are free on the turn that a new Civic is completed.

The "Legacy Bonus" is a % bonus that accrues the longer you stay with a particular government, but which you keep even if you later change governments.

"We allow you to re-slot policies for free every time you complete a Civic. You can do it anytime you want, it just costs some gold if you're doing it between turns. For a culture player, there's a large amount of Military-specific policies that you can get. If you're a Military-focused player, you might not have as deep a lineup of policies, because you're mainly playing science. As a culture player, you'll have those abilities. You'll be able to produce units 25 percent faster as an example. You can react to stuff pretty quickly. If you're really far behind there may be no hope, but there's a lot of knobs a player can turn to get a lot more defensive ability." - Dennis Shirk
