Thanks for the article! I found it most useful, using it as a guide to win my first King and Emperor wins consecutively (as Genghis (what a waste of unique abilities/units) and Napoleon respectively), although I went for two cities in both. I managed to get the Oracle both times; is this simply not nearly as possible on Immortal or Deity? And I got the Sydney Opera House both times with only one or two policies remaining (RA beeline after Telegraph and Radio). Is the fact that I got this indicative of being too slow wrt culture (I ended up winning both games about turn 320)?
Also, in the Napoleon game, I had a bit of a hiccup with my neighbour, Julius, declaring war on me having been Friendly the whole game, without any warning. I managed to see the attack off by upgrading my warrior to swordsman and rush buying a knight (extra benefit of the Chivalry slingshot, I guess). He was underdeveloped, so it was easy enough and I got gold and resources out of the peace. But it strikes me that there was nothing I could've done to prevent this attack, and the only reason I saw it off was that Julius was still with warriors, spearmen and an archer. Is there a more foolproof method of preventing such greed attacks that I'm missing?
