I'm enjoying the patch so far as well, but the AI still seems to be pretty bad. I'm playing on Soyuz difficulty and winning --- just to show you how n00bish I am, I have never won a Civ game on the second-hardest ranking before (Emperor or Deity), and yet I am doing so quite easily in this game. The AI just sent about 8 ships to attack my coastal city without a single land unit to actually take it over after it easily reduced my city to 0.
