I decided before the game to go for a Diplomatic victory. I figured that due to the Aggressive AI, I might not have a ton of competition for this. Of course, I was going to going for diplomacy by the sword.
On the first turn, I built Bibracte in place and started building a worker and researching Animal Husbandry. I lost my Scout to a bear in 3700 BC, which was rather annoying.
After scouting, I decided there were basically three very good city spots within potential grabbing distance. The first one was the Horse/Clam/Corn/Whale spot to the north, the second was the Gem/Fish/Banana spot to the south (this was before I knew it had copper too) and the third was the Rice+uber Ivory city to the east. Persia grabbed the Gem/Copper city before I even built a settler, so my first settler headed north to the Whale/Corn spot and grabbed that. My third city filled the gap between my two cities and also shared the cows with my capital. Before long, that city coopted the cows for the rest of the game while my capital made do with the corn.
At this point, Persia had also grabbed the uber ivory spot, and there were only two potential city sites left to me, the single ivory site to the east and the coast to the south which also could grab bananas. Both were pretty heavy with jungle, but that was ok as I had planned to go for our special unit anyway and was already researching my way towards Iron Working. For my 4th city, I built next to the solo ivory, including the rice in my outer radius, although my culture for that never overtook Persia. Finally, I built along the southern coast for a 5th city.
My starting research path was as follows:
Animal Husbandry -> Agriculture -> Mining -> The Wheel -> Pottery -> Bronze Working -> Iron Working
I had planned to go to Writing then Alphabet at this point, but after seeing that I had neither copper nor iron, I decided to research Horseback Riding so I could fight with Horse Archers. If I had thought about this some more, I would probably have not bothered and beelined for Construction to build Elephants. While researching Horseback Riding, I built half a dozen chariots for defense.
My research at this point was
Horseback Riding -> Archery(oops, forgot I needed this!) -> Writing
I was just about to start researching Alphabet when I found out that a couple of the AI already had it, so instead I picked up Metal Casting. Once I got metal casting, I was able to trade for Alphabet, Mathematics and all the little techs I missed. I then proceeded to start building Construtcion.
I failed to make good use of Horseback Riding, only building a few Horse Archers. My cities were instead mostly preoccupied building Stables right after I got Horseback Riding then Forges after I got Metal Working. Actually, I guess being able to build those Stables early wasn't so bad and going Horseback had the unintended consequence that I ended up not reasearching Alphabet, which probably helped me. Once I got to Construction in 95AD, I started pumping out War Elephants and Catapults as fast as I could and set my research towards getting Liberalism. By 635 AD, my War Elephant force was ready and I declared war on Egypt.
