Table usage[edit | edit source]
Color indicators: Starter , Acquisition , Rare , Dangerous , Repeatable .
Notes:
- The table shows the default names/icons of techs. Flavor entry is displayed if accompanied by a change to effects/requirements.
- If a tech has been available as a research option as part of the last choice, then its (total) weight will be halved in the coming choice.
- The table denotes the base cost of a tech. Actual in-game tech cost will scale with the empire's size (number of colonized planets and population).
- The
Technocracy civic doubles the weight modifier for leading scientist expertise traits. - To research techs of higher tiers it is first needed to acquire 6 techs of the preceding tier.
- Sorting the table by tiers will place all Starter tech at the top and Repeatable end-game tech at the bottom.
- Most icons also double as links. For more information about an unlocked effect (buildings, components, etc.), click on the accompanying icon.
