Started by migrating. My scout got some gold from the hut near the Viking start. Didn't explore any more huts the entire game (except one on a Pacific island in the 1400s which yielded some hostile villagers). Settled first settler one spot southeast of the copper allowing access to copper, silver, stone and two fish. Settled the second settler at north end of the Gulf of Finland granting access to fur and deer.
Built up some basic infrastructure, then built some axemen. Herbalist event (testing herbs on your people) led to one extra happiness for ten turns. Only got two other events the rest of the game. In 975BC (near the end of my war with the Romans) a volcano exploded near my capital wiping out my only connected copper mine, my only silver mine and my only stone quarry. That meant I couldn't train any more axemen until I managed to rebuild, but fortunately I had already built enough axemen to finish off the Romans. I got a Great Spy around 1300 AD; don't remember seeing the event, but he suddenly showed up in my capital. Didn't end up using him.
2800 BC. Egypt finishes the Great Wall; this was one of the three wonders I wanted for the game. Fortunately Egypt is not too far away. I'll deal with the barbarians until then.
Russian War (2325BC-1925BC)- conquered Russians with axemen. Unfortunately they already had archers, but I overwhelmed them with numbers.
Roman War (1500BC-925BC) - conquered Romans with axeman.
I finished The Great Pyramids in Moscow (1375BC) allowing me to switch into Representation for an early happiness boost. I finished the Great Lighthouse in Nidaros in 1200BC giving me a financial bonus.
Joined the Hindu religion along with Ramses, Mansa Musa and Shaka; Shaka had feudalism (and likely longbowman) and Mansa had skirmishers. Buddhist block of China, Khmer, Mongolia and India does not seem to have feudalism, which should make the Buddhist block easier targets
Attacking Egpyt with axemen would be suicidal, so I started building horse archers.
Egyptian War (260BC-80BC) - I whipped some horse archers and attacked Egypt. They built the Apostolic Palace in 245BC. I whipped a few more horse archers before they got a chance to use the AP. I didn't whip anything for the rest of the game
Indian War (40AD-100AD) - India only had three small cities left as the Mongols had taken over the rest of their cities
1st Khmer War (145-280)- I was waiting for knights to attack the Mongols and the Khmer didn't have many cities, so I figured I try to take them over in the meantime with horse archers. I knew it was didn't make sense to attack them, but at the time I just felt like attacking. I took over one city and them watched my horse archers get bogged down in the uncleared jungle and a bunch of them were killed by spearmen. I made peace because I was not making any progress and I started getting a bad feeling about leaving my other cities exposed.
I switched to mercantilism and caste system in 340AD.
Mongol War (385-700) - I had recently finished researching knights when Genghis declared war. It would have made sense while I was stuck in the jungles of Southeast Asia, but at this point it was just stupid. His stack of doom was massacred by my stacks of horse archers along with a couple of knights I had managed to upgrade from horse archers. After that it was knights killing archers. Mansa and Shaka joined the war near the end.
Switched to mercantilism and caste system to go with representation
1st Zulu War (715-910)- I was planning on attacking China as soon as the Mongols were subdued, but Shaka changed my plans. His stack of doom that was advancing to Mongolia must have been upset when the Mongol War ended because on the next turn they took over several of my cities in the Middle East. I had to redirect my knights and lost a bunch of knights in suicidal attacks in an effort delay the horde from advancing on Thebes (renamed Cairo), which contained the Great Wall, Apostolic Palace and several other wonders. I wasn't really worried about retaking any cities, but was worried Shaka would raze them. Took over about one third of the Zulu cities before making peace.
2nd Zulu War (1070-1110)- I took over all the remaining Zulu cities with cuirassiers with exception of one on Madagascar (didn't have a navy at the time)
Mali War (1220-1290)- conquered Mansa with cavalry
3rd Zulu War (1285-1290)- conquered the last Zulu city
2nd Khmer War (1310-1320)- conquered the Khmer with cavalry
Chinese War (1335-1400) - conquered with cavalry
Maya War (1410-1440) - bombarded costal cities with frigates; conquered cities with cavalry; left Pacal with the Falkland Islands
Inca War (1440-1460)- bombarded costal cities with destroyers; conquered cities with cavalry; made peace leaving Huayna Capac with one small city
