Thank a lot everyone!
I picked warlord difficulty, because its been a while since I played last time, and because I am new to the expansion. I'll be moving up the difficulty in my next game. I'll also make sure to build more cottages too. Now that i've captured Justian and Catherin's land, my finances are hurting, but I did cottage every green tile insight, so things should be getting better. I am getting 500+ beakers per turn and its about year 13 hundred something.
So my current plan is to sail across the ocean (since I have astronomy now, and way ahead of all the other rivals) to the other guys, and vassallize them.
