Overview
Use the full shared technology and unit tree for civilizations in modes that support this option.
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
Use the full shared technology and unit tree for civilizations in modes that support this option. An Age advance unlocks new units, buildings, and research, but costs resources and occupies the Town Center. Plan the timing against the need to keep producing Villagers and defending the current economy.
