The point is not that it looks like AOE-3, the point is that various mechanics that AOE-3 proposed could be rescued, such as:
Livestock (this is not well developed in AOE-3, but at least touches the subject a bit).
Alliances with foreigners or with local populations: For example, Asians can ally with foreign powers in AOE-3 and obtain bonuses, technologies and units from those civilizations. You can also ally yourself with local towns that are on the maps. It will be viable in any era of human civilization because, for example, the Romans had barbarians integrated into their armies.
Multi-option ways of advancing age such as the US that integrates states: For example, Gresia could have a way of advancing age that resembles that of the US or Mexico where, for example, it could advance to the next age integrated ‘cities - states’ (Athens, Sparta, Corinth, Thebes, Syracuse, Aegina, Rhodes, Argos, Eretria and Elis.). Every time you choose a state you will get certain bonuses, but you give up others.
