A long evolution starting at King Level and quite militaristic, to the present Deity/Deity+ unabashed Capitalist whose sometimes also militaristic, sometimes quite pacifist.
Tend to play perfectionist in the early game, integrating more expansionist tendencies with the acquisition of the early Modern "triad" (Explosives, Democracy, Refrigeration). Almost never build defensive units nor city walls; and almost never build temples (except, of course, when I'm rush building a unit from scratch). Marco Polo's, Hanging Gardens, and the Colossus are the first three Wonders built. Never build the Great Wall, the Great Library or the Pyramids. Never really bother with the Super Science City anymore, relying on creating the World Trade city. Initial tech research targets Republic and Trade -- though I will go Monarchy if I happen to run into a hut. From there to Monotheism and Navigation for their commensurate wonders, by which point I have become a "Merchant Prince" of the Republic. Trade, trade, trade ...
Following acquisition of the early Modern triad, I reduce the science budget to 0% and prime my civilization for the shift to the Modernization phenomenon; i.e., double (at least) the number of engineers, lay in a supply of quality caravans, build markets and banks, and delay acquisition of the Railroad and Industrialization, primarily by researching the "neglected" military techs of Chivalry through Tactics. After around 25 to 40 turns of this, it's time for Rostow's "take off," using Darwin's Voyage for the quick transition from Railroad to Corporation which, with Leonardo's Workshop, upgrades all of my quality caravans to quality freight. And, having reached this point, and with the full-blown Power Democracy fully established, there's just no looking back.
Still stalking a "perfect" game ...
