There are very few techs that require you to have 2 different buildings.

Each tech has a specific theme that either gives you something new to use, or augments something you already can build.Īge of Empires has techs as well, but instead of a vast tree that spans the ages, it's more of a shrubbery: you build a new building and that building gives you the option to research a new tech. Some techs require more than 1 base tech to unlock. You then have a choice of about half a dozen other techs, each of which can unlock other techs. Tech treeĬivilization 5 and other 4X games have an extensive tech tree: you start with a single technology unlocked in the very first part of the game. Comparing the 2, these are some of the differences: 1.

I have played both Civilization 5 and Age of Empires extensively.
