The technology tree, more commonly known as tech tree, shows available units, buildings, and technologies for a certain civilization in Age of Empires, Age of Empires II, and Age of Empires IV. Each civilization has its own unique technology tree. Unless the square All Techs (unavailable for Age of Empires IV) is checked in the settings prior to the beginning of the game, only a limited number of units, buildings, and technologies are accessible for every civilization. However, doing so also eliminates civilization bonuses for every player.
Every game's technology tree can be found at its respective page:
- Technology tree (Age of Empires)
- Technology tree (Age of Empires II)
- Technology tree (Age of Empires IV)
In Age of Mythology, each civilization has a completely different technology tree.
Similarly, in Age of Empires III, each civilization's technology tree greatly differs by the region. They are currently divided into 5 parts (Africans, Asians, Europeans, Native Americans, and Federal Americans).
