Founded 3 cities -- settled Carthage in place, and two others in desert tiles to West (near Warsaw--settled on the sugar) and Southwest (near Brussels, settled on riverside hill, between the two sugars). Full Tradition opening, and about to open Honor.
Took Constantinople on about turn 80 (forgot to note the precise turn number) and Berlin on turn 106--initially took and razed one secondary city apiece (they were on my path to their capitals), but left both civs with a secondary city (not worried about the diplo penalty for elimination, just didn't want to burn the turns to take those cities and then raze them). For that campaign I used a bunch of CBs, one warrior and one spearman (a catapult did arrive in Berlin just in time to deliver one shot on the city before it fell).
Dragged that army back to my cities (I've got to build more roads, or this is going to take forever), built another catapult, a couple more CBs and spearmen, and upgraded two warriors to swordsmen with iron from my new ally, Tyre. I'm one turn away from Machinery and a mass upgrade to Crossbows before I march on the Mayans, Dutch and everyone else.
Got desert folklore as pantheon. Founded first, took tithe and shrine happy, used a missionary to convert my two secondary cities, and then enhanced with religious texts and shrine/temple food (the remaining follower beliefs were kind of crappy), but I don't think this game's gonna last long enough for religion to move the needle.
I've focused on the bottom of the tech tree, messed around getting to Philosophy and the NC, and still don't have Civil Service (and I do want to upgrade my spearmen to pikes), but I'm still competitive tech-wise near as I can tell (mostly based on what wonders are going -- Pacal just finished Notre Dame for me, thank you very much! I expect I will need the happiness).
I didn't research sailing and optics until around turn 100, so I'm going to start building melee ships and, once I get Compass, galleasses to help take some coastal capitals (near as I can tell, most of the capitals are on the coast, but some look easier to take by land given how this continent is laid out -- but this is a long, snaky continent, so some naval support will likely be necessary).
