The map is anatolia and we both start fishing on the same side. I didn't want to build more than 2 docks on each side, while my opponent built 3 docks on just one side, so he won the sea battle on that side. However he didn't build a dock on the other side so i was able to boot boom in the quiet water and my economy could keep up with his.
In late classical the fighting for the middle begins and continues in heroic. We both fail to use our GP effectively. He spent his frost on only a couple of my units and eventually lost that battle. Then i want to cast WW to finish him quickly and cut off his last gold supply, but this time he's the one to win the battle and the war continues. I built a TC on one of his settlements and he wants to do anything to get it back. This is also the place where his gold miners were, so for me it was worth fighting for as well. He destroys my TC and hillfort but he's not able to keep my troops away and i eventually win the final battle.
