Age of Mythology: Retold

You can complete this quickly, its possible to just reload a save. its how i did it:

Skirmish with one AI on lowest difficulty, infinite ressources, game speed set to normal or fast, its up to you.
choose any God you like it doesnt matter, i took Poseidon, advanced to ages 4, built a few temples and just spammed a ton of hydras on the AI base for fun
Remember to make a manual save just before killing the last units/buildings. If the AI want to surrender, choose yes.
When the winning screen appear, press quit and you will be sent to the main menu. from here press Continue and it will load your previous save, just repeat until it pop. if your save is bad, you can always make a new one closer to the win.

Note that this methode work for any achievements which doesnt ask to do the requirements in a single game.
i reloaded a save a couple time to kill 100 villagers with Fenris wolf or for the Caladrias healing.
