Technology tree
A civilization-specific chart of available units, buildings, and research across the four Ages.
Overview
A civilization-specific chart of available units, buildings, and research across the four Ages.
How this system affects decisions
Treat research as a sequence of choices: check its building, Age, prerequisite, cost, and the units or economy affected. An upgrade is most valuable when it arrives before the army needs it and improves enough of the units already in production; researching every available technology is rarely the best use of a limited stockpile.
How to use this reference
A civilization-specific chart of available units, buildings, and research across the four Ages. Research availability is part of the civilization’s tech tree: verify its required building and Age, then compare its cost with the units or upgrades the same resources could otherwise fund.
