Table usage[]

Color indicators: Starter , Acquisition , Rare , Dangerous , Repeatable .

Notes:

  1. The table shows the default names/icons of techs. Flavor entry is displayed if accompanied by a change to effects/requirements.
  2. 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.
  3. 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).
  4. The Technocracy civic doubles the weight modifier for leading scientist expertise traits.
  5. To research techs of higher tiers it is first needed to acquire 6 techs of the preceding tier.
  6. Sorting the table by tiers will place all Starter tech at the top and Repeatable end-game tech at the bottom.
  7. Most icons also double as links. For more information about an unlocked effect (buildings, components, etc.), click on the accompanying icon.
