All Cities and or Outposts will have a list of items displayed on the right-side panel, which can be finished/completed through the Construction Queue of the city or the outpost; these items are collectively known as Constructibles.
There are three ways to finish or complete the Constructibles:
- City Creation (Ancient Era, no technology required)
- Colony Model (Medieval Era with Feudalism technology)
- Colony Plan (Early Modern Era with Three-Masted Ship technology)
- Colony Blueprint (Industrial Era with Steam Engine technology)
- Colony Grid (Contemporary Era with Civil Engineering technology)
