I gave Khmer a try and focused on a Warrior Monk rush. It was interesting. I got hard hit by barbs and hand only Montezuma in neighborhood (city states were all on the other side of him and Indonesia as I was to discover). I just managed to get a religion but didn't have any culture bonuses so it took a long time to get to Theology for the temple and apostle. Still the warrior monk go through Eagle Warriors nicely. Walls are another matter but a battering ram did the trick. As I finished off Monty I discovered that Indonesia was behind him and that I would be attacking from the land - how hard can they be without having to face their Jongs? Well it was fine until the knights showed up. Monks don't fare well against knights. I could handle the odd being careful. But the walls were too tough. So I had to wait for the Domrey Elephants. They are pretty nice - the move and shoot is really helpful and they can handle the level 40's walls nicely. It was hard work but I got there in the end - finished off with control of my continent and then held on for a culture win. The monks are really tricky. You have to get your religion and culture up fast to get them in play quickly. But they don't last long. Their first promotion is pretty weak and it takes a long time to get the level 2 and 4 promotions that give them staying power.
