Just finished a 3000 B.C.E. Khmer game. I wanted to play the game without doing the caravel chain, there is a quicker way. Therefor I loaded up the game until the start up was favorable. The first time I loaded it I was trapped between a very strong India and a very strong China. Along with that Pagan had been destroyed. So I loaded it up a second time and got a much more favorable start up. India had collapsed, with two of their cities independent, Dilli and Lahore. Pagan was independent and China was still around, it is important to have China. I settled Bang Makok on the sugar, Hanoi four squares north, and Jayakarta. Later on I settled Hariharalaya near Russia. This was important to make sure nothing happened to me road, and it was a good city to produce missionaries and send to Europe. In fact by the end of the game it was my best production city. The location is a bit South East of Russia with iron to its North and wheat to its West. For the record I did not come up with this city idea. It was TDK's and you can see his strategy on page seven or eight of this thread. I then captured Dilli and Lahore. Dilli of course is important because it is the Holy City for Buddhism, important for the economy. Luckily the Mahabodhi was already built there, it then soon generated a Great Prophet which I used to build the Kashi Vishwanath. Persia was mostly Hindi so it helped my economy even more. My civics were Slavery and Hereditary Rule and I never got around to changing them. This is because the only reason I would change them would be for Pacifism and Caste System. However neither of these were useful for converting people to Buddhism. Pacifism would require me to get a state religion and then be on negative terms with pretty much everybody else, and I never got around to getting Caste System as I stole Feudalism rather late from Arabia. Anyways, since there is no Silk Road in the 3000 B.C.E. start I decided to create a new road. This road would go from Indonesia to India, only needed one more square of road to complete, India to Persia, was already built, and Persia to Russia. So I sent two formerly independent workers to build the road. With Engineering I was able to send a missionary from Bang Makok to Moscow in six turns, I do not know the amount of turns using the silk road though so I can not compare. Neither China nor Persia had Engineering so I had to research it myself. I got Drama at around 1200 C.E. and immediately whipped theaters in all of my cities. I was able to produce two Great Artists, since I did not have Pacifism. I settled one in Jayakarta and one in Dilli. The rest of the culture was just culture gained over time, the majority of it coming from Dilli. I have no idea how to show the culture of every city at once so I will just list the cities and their culture at the bottom, by 1430 I had a total of 12060. I achieved thirty percent Buddhism by 1405, and average population of twelve by 1420, my culture UHV requirement can easily be improved, which of course was 1430. The UHV is posted below along with the Buddhism proof and population proof.
Culture in cities: Jayakarta-4560, Bang Makok-842, Pagan-133, Hanoi-405, Dilli-5630, Lahore-430, Hariharalaya-60. = 12060 culture. If someone can come up with an easy way for me to prove it, i.e. one screenshot, then I will post that.
Edition: I forgot to mention who I spread Buddhism to. First I spread to all of China and the major cities of Persia. Then I was able to convert Japan after Buddhism spread to their capital be random chance. After that I spread Buddhism to Russia, Germany, and The Netherlands.
