Played a 7 hour game with only minor breaks for munchies and restroom. Impressions (played up to 1875, or thereabouts):
AI Aggressiveness: Dudes (and dudettes), there's nothing wrong with the bloody AI on a normal setting. Hannibal, one of my neighbors, DoW on me numerous times. Babylon and Ghandi played nice.. most of the time, when they weren't being nasty to each other, that is.
Barbs: Raging barbs, noticed no difference pre-patch. They're still a pain in the butt. Thank God for the Great Wall.
Espionage: Since we were all on separate continents (small map, 4 landmasses, total of 4 civs including myself), there was very little spy activity. I used 3 great spies to infiltrate, but that's about it. Pity there isn't a spy ship like SMAC's SeaProbes. That would be so useful. Not sure the AI knows how to use spies over the water.
Bugs: Black screen glitch on diplomacy, as listed in the bug forum; was using Bhruic's latest patch so that took care of the majority of the display probs.
Tried for a diplo victory. No matter how many times I was nice, giving gifts, money, et al, I simply could not bribe them to support me. Darn AI is as stubborn as the real life tinpot dictators that infest the real UN.
This is a real challenge, and I'm only playing Noble to get my feet wet with the new features. I'd be willing to bet future games are going to be headaches.
Odd event I did have: when I shut the game down, the OS complained of low virtual memory. Given I only have 512mb Ram at the moment (another 512 stick on the way, and have 128mb graphics card), I'm not surprised. The paging file is set to a max of 4gb, which is why I call it odd. I wonder if there's some kind of memory leak in this patch? It could be that I'd forgotten AVG was updating at 4am, and got caught in the middle of a war with it updating on me, so I don't know. *shrug*
All in all, with Bhruic's patch, this game has become challenging.
