According to Myers-Briggs, Im an INTP, one who has been described as many things started, few games finished.
For Ace, I enjoyed the recent GOTM game on the world map by starting as an OCC, but bailing out. Developing a civ stating around 1500 AD (my second city -- bloodlust mind you) lets you have the tech to be competitive, but the rest has to be built up. Needed the howies to pull it off. I have the save when I bailed if you want a late start into the modern era
Of course that might also be a reasonable GOTM premise -- The duke plays until 1000 (maybe 1300) AD or so as an OCC, but bails (perhaps as a mole?) -- all the other civs have equal tech due to tech gifting, the player gets a reasonably developed SCC, but maybe has an atrocious reputation in an otherwise bloodlust game; natch Mike, Leos, probably JSB are all elsewhere
