I tried a couple of test games with with the GOTM settings. Couple of things I found: 1. If you go for early religion and you're ruthless with chopping everywhere, you usually can get an early religion, and it's not too hard to go for the religious-path wonders. (On one of my test games, I managed to build all four of them - stonehenge, parthenon, pyramids, oracle. I later followed up by building versailles and spiral minaret - good progress towards a cultural victory!). 2. The ice-age land seems to have a lot of tundra and plains and very little grassland, except near the equator. That means cottage-spamming is a lot harder to do - there are relatively few city sites that have enough food around to prevent you having to farm (rather than cottage) the plains. I was relying a lot on fish/clam/etc. for food. In general, I got the impression you have to think a lot harder than normal about where to place your cities so they'll be able to grow AND give you an income. 3. Be careful about AI's huge military power on emperor. Today's practice games were the first ones I've really tried on emperor. Overall I got the impression it's not too different to monarch - except when you go to war. The one extensive war I tried was I thought a textbook example of how to plan it. I had my state religion in all but one of Alexander's cities so I could see how big his army was. I bribed Monty to declare war on Alex, then spent about 5-6 turns waiting and watching the events. Then, once I could see loads of Alex's units tied up with Monty, I attacked. Yet despite all that, within 2-3 turns he just had dozens of units, apparently turning up from nowhere. Not only that, but the turn I went to war, he had *nothing* more advanced than swordsmen and horse archers. About 3 turns later, every other unit of his seemed to be a maceman (though only on my front - he was still mostly throwing horse archers at Monty. grrrrr!). I ended up having to completely retreat to regroup after taking just one city and pillaging his iron. I don't know what the bonuses the AI gets are, but if that's typical of emperor-level wars, then wars are going to be very tricky in this GOTM.
