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 in the 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. To research techs of higher tiers it is first needed to acquire 6 techs of the preceding tier.
5. Sorting the table by tiers will place all Starter tech at the top and Repeatable end-game tech at the bottom.
6. Most icons also double as links. For more information about an unlocked effect (buildings, components, etc.) click on the accompanying icon.
