Aom retold has been reworked with a "new" engine, the same one used in Age of Empires III Definitive Edition, in addition to all the graphical and interface reformulation, in addition to all the remade music. We will also have new gods in the pantheon, such as Freyr, and in the first expansion we will have the Chinese civ, and a new civilization not yet announced for the second expansion. Some important changes in the gameplay such as the increase in the maximum population, being able to use the divine powers more than once (like it works with the Atlanteans), and also being able to activate/deactivate the powers of the mystical units, so you can choose the moment you want to use them. There also seems to be a more effective rock/paper/scissors system now, for example, the Greek hoplites had no bonus against cavalry, now they do.
