"Everyone builds on other men's failures. There is nothing really original in science." —Daniel Keyes, Flowers for Algernon

Trunk technologies

Powerful, yet slow and costly, Trunk technologies represent fundamental changes to your faction's society, granting new units, buildings and abilities — for instance, researching Mechanisation unlocks more powerful aircraft and tanks, while the penultimate Trunk tech, Atomic Power, grants access to nuclear bombs.

Science research 

Unlike Rise of Nations, Science research needs oil in order to operate. AND a lot of it too. Although the first 2 or 3 tiers will cost knowledge not oil, other tiers will soon require much oil in addtion to be successfully researched.

Commerce research

Timber is no longer required. Rather, food will be required to complete commerce research.

Civics research

Civics research increases the number of cities you can build and also unlocks various buildings, units and upgrades in conjunction with other tech tracks, but the most common use for it is expanding your effective control of the land through your cities.

Note

Previously, Food was required, but its place has been taken over mainly by Wealth.
