Complete Guide to All Civilization 7 Technologies and Tech Trees

Choosing the right technologies to prioritize is crucial in Civilization VII. This decision affects both legacy requirements and the establishment of successful towns and cities. To master the game and tackle the more difficult victory conditions, a comprehensive understanding of the Civ 7 Tech Trees is essential.

Each age within Civilization VII features its distinct Tech Tree, necessitating players to unlock specific technologies to access others. As time management can be challenging, plotting a strategic path to important technologies is vital, especially for players aiming for a Culture, Economic, Military, or Science Victory.

Players can access the Tech Trees in-game by selecting the “View Tree”button while in the “Choose a Technology”menu. This feature provides valuable insights into available technologies.
