[0] 1550AD - First, I rename Neapolis R5, because that appears to be its logical number.
Next, I wake up some sleeping workers and make them road some tiles.
Next I upgrade some catapults to cannons.
Next, I take research up to 50%, so we get Banking in two turns. With our economy, we really need banking, and I don't think we should abandon all home-land buildup entirely, just in case Alex or Mansa pull something funny.
I also rush the courthouse in R1, because it's got a whole lot of population, and also a whole lot of maintenance cost.
[1] 1555AD - We take Berlin and with it - the life of the German people.
The remaining troops start marching for the Greek lands.
[2] 1560AD - We get Banking, start research on Paper.
[3] 1565AD - Time to start the ol' war machine rolling again.

I declare on Alex.
[5] 1575AD - Ooh, look, a Greek SoD appears. It consists of three Knights, a mace and a cat.

(Also, a cat attacks one of our stacks IBT, but dies.)
The city of Ephesus burns at the loss of one cannon.
The city of Herakleia is taken at no losses.
The city of Knossos burns. No losses. We do, however, enslave some Greek humans and send them to toil for the betterment of our homeland.
[6] 1580AD - We get Paper. Start on Printing Press.
The city of Thessalonica burns at the loss of a cannon.
The rest of the turns are spent setting up an attack on the next Greek city - the one with the Spiral Minaret, and that is the Christian holy city. Now, it is at 0% defense, and has only a few wounded defenders. Should fall easily next turn.
Also, we are running 30% science and are in the red.

However, the Forbidden Palace will be completed next turn and a bunch of Banks, so that should help us out financially significantly.
Good luck, Ham. You can probably largely eradicate the Greeks in your turns. Who knows, maybe this game won't even make it back to me again.
