I think that here I did 2 main mistakes: Forgiving him on water and not exploring his base, where his villagers are, and don't raid them to weak his econ... Also letting him conontrol all the mines in the map was a mistake, when i tryed to take them back i didn't have enough gold to do that.
This is a recorded game of the vanilla version AoM, so it won't work on the titans
Thanks for watching and enjoy
