So I'd choked both the Holy Roman Empire and Arabia, then HA'ed both of them out of existence. I got greedy with cities and had to crawl to Currency to avoid losing units to strike.
I ended up using 3 Great Generals as Super Archers, one as a mobility Super Medic (on a chariot), and the next four all settled in the capital. Turns like this weren't uncommon"
So with the special promotion for double combat XP that's easily 12+ XP every few turns. Leading fairly quickly to this:
I infiltrated Babylon with my GSpy, bulbed Alpha with my first GScientist, finally got through Currency and then CoL myself by building research/wealth and some help from Rep scientists thanks to the 'Mids
From Babylon I've stolen Construction, Poly->Mono->Monarchy and at long last:
Now I am safe for a while, with the free upgrade to LBs for my three SuperDefenders. Genghis is being very nice and teching straight from Feudalism to Civil Service, another big one I won't have to do myself. That and IW will probably be the last techs I steal, hopefully with enough Espionage Points left over to incite revolts in a few cities.
Here's what the capital looks like:
Having had half it's cottages pillaged down to nothing

Shoulda expanded west like BiC did, oh well. Our second best city is the former HRE capital:
A potential spot for the Heroic Epic if I ever make it to Literature. Even though the capital has 4 settled GGs already, Aachen can get better production and I won't want to whip it either.
Here are the game stats so far, sorted by units/buildings/improvements built:
