Pregame Planning
I decided to move the settler south to scout and then, if no reason to move further appears, the worker will mine the start tile and I'll settle on turn two.
I decided to play an "always war" game. I.e. on first contact with each rival, I must declare war on that Civ and then never agree to peace. I may not make any gpt or luxury/resource trades before declaring war. (See Arathorn's
Comprehensive Guide to Variants for a description of this and many other variants.)
I also decided to try for a Diplomatic victory. If I don't get it on my first try then I'll have to finish the game another way. To make this possible at all I'll make one change to the always war rules - I'll allow making peace with other Civs on the turn before building the UN.
Since I haven't played an always war game before I did some extra planning before starting.
My usual rapid expansion type of opening would be a very bad idea with always war - it would result in more towns than I could defend. I'd have to start with a military buildup. No new town should be founded until I had the strength to defend it.
Aggressively attacking an early rival seems like a bad idea with always war. Such an attack is best done by applying most of one's military. That would leave my home region poorly defended and I might have a few other rivals coming from different directions. I think the best way to start will be to wait for my rivals to come after me.
I won't want to explore immediately. The longer it takes until I meet rivals the better - more time to prepare for their attacks and more time to advance in tech and take advantage of the one and only trading opportunity with each.
Initially I thought I'd begin by building Jaguar Warriors and using them for an early military advantage. After thinking things through I changed my mind. Jags are fine for exploring but I won't be exploring. Jags are good for rushing a rival but I won't be doing that either. The loss ratio with Jags is high - affordable against one rival but seems bad against a number of rivals at once. I want my military units to survive the large majority of their early fights. And finally, I'll prefer to avoid an early Golden Age. It might be necessary if I'm pressed hard by multiple rivals. But if I can do without it, which seems likely at Monarch level, I'd rather have it later.
I decided that my forces in the early game would be archers at home, and then archer/spearman groups when I explore and expand. Archers at home because I'd rather attack incoming rivals on ground of my choosing than defend against their attacks and allow them to pillage.
I decided to start by building barracks. This is a gamble but a very small one I think. The militaristic Aztecs can build a barracks at half price - it is quite unlikely that another Civ will meet me before it and a unit or two are complete. And with a lot of fighting coming, veteran units will be helpful, as will promotions to elite and chances for leaders.
Research will of course be a problem. No trades after first contact, I'll have to learn everything I want, and do it without any trade income from other Civs. It seems to me that two approaches are possible. 1) Lag a bit behind in research. This is probably the most effective approach - after my rivals know a tech I can research it more cheaply. That would make it easy to maintain four turn research a lot of the time, picking up techs quickly to make up for my rivals trading among themselves. 2) Try to get ahead in research. This is more difficult. I'll need lots of commerce and will have to invest shields in libraries and universities.
I'm going for a diplomatic win. And of course I want it at as early a date as I can manage. It will take the AIs a long time to reach Fission on their own. So I decided to go for the second approach, to try for a research lead.
If I can get the Great Library it will help a lot, keeping me caught up in Ancient Times and getting me some optional techs. I decided to try for it.
The Aztecs know Warrior Code as a starting tech so I'll start by researching Bronze Working to make spearmen available. After that I'll research Alphabet, Writing, and then Literature, to get to libraries and the Great Library asap.
I expect to be in Monarchy from the time I learn it to the end of the game. A Republic in an always war game would soon have maximum war weariness from every rival and that would be a huge problem.
I will avoid razing any cities to maximize my chance for a diplomatic win. I might get away with doing it with early rivals but I don't want to gamble on that.
I'll want to completely eliminate any Civ I have extensive war with, particularly any Civ whose cities I take. Up to a certain point warfare doesn't permanently damage the relationship with an AI. But after taking some cities it is unlikely they'll ever be friendly again. So they must be destroyed or they'll block a diplomatic win.
The Ancient Age
I moved the settler south and built Tenochtitlan there next turn. The worker began by mining and roading the start tile, then moved to do the same on two other BGs.
My build sequence was barracks, archer, archer.
As soon as the first archer was complete I sent him a bit east, exploring ring 3 sites for my second city. Unfortunately this resulted in spotting an American warrior. I traded for Pottery then declared war.
After building the second archer I decided to gamble on squeezing in a granary build. While building the granary two American warriors approached and I took a risk. I could flip the granary build to a spearman or gamble on my archers. It was likely (2 out of 3) that I'd defeat both warriors without losing an archer. If I lost one archer odds were high that the other warrior would be damaged and my remaining archer would win. If I lost both archers (1 in 68 chance) then this would be one of the shortest games of Civ I've played. Both archers won, phew.
After building the granary I built spearman, archer, spearman, and finally a settler in 2070BC. By this time I'd scouted the available ring 3 sites. My second city went to the northwest where it could claim the wheat after building a temple.
I then built up military for a while. No further American forces arrived until 1700BC and by that time I was in little danger from invaders - I had 4 archers and 3 spearmen, all staying near my two towns.
In 1675BC an Iroquois scout came into sight and I declared war. I also saw my first barbarian at that date.
In 1325BC my third win with an elite unit produced a leader! I had a prebuild for Great Library in the early stages - I had it build a granary and I saved the leader. In 1100BC I learned Literature and the leader rushed Great Library. It considerably simplified my research of course - in 1050BC it gave me Masonry, The Wheel, Iron Working, Mysticism, and Horseback Riding.
My QSC status (1000BC):
4 cities (the capital and three in ring 3)
2 granaries, 3 barracks, 2 temples
6 native workers, 2 captured workers
6 archers, 4 spearmen
1 Great Library
47g in treasury
My world looked like this at 1000BC:

Iron soon became a concern. Both America and Iroquois had iron but I did not. A group I sent to explore the Iroquois lands encountered a swordsman in 850BC while they were retreating home.
I decided to set up for a horseman rush on Iroquois to take their iron. I didn't know where that was but presumably I'd eventually find it

They didn't have horses (at least, not connected yet) so by hitting them quickly I might avoid their UU and avoid triggering their Golden Age.
During this time I researched Polytheism and then Monarchy - I didn't want to wait until I received Monarchy from the Great Library.
My losses of horsemen against Iroquois swordsmen were heavy but in 370BC I captured my first Iroquois town, Niagara Falls. And in 310BC I took Salamanca and its iron.
I slowed my attack at this point. I wanted to pick off another Iroquois town or two but all the towns I could see were size one. I had to wait for them to grow in culture or population to avoid razing them. During this phase I got a second leader in 210BC, from a spearman while defending. Nice. This leader rushed Forbidden Palace in Niagara Falls.
I learned Monarchy in 150BC, flipped immediately, and triggered my Golden Age with a Jaguar Warrior.
I used my Golden Age production mostly to build barracks, horsemen, and libraries. My progress against Iroquois was slow but steady. In 70AD I got a third leader. I used him to rush Hanging Gardens. That's usually not a priority for me but in this game I'd have problems getting a lot of happiness - can't trade for luxuries. So Hanging Gardens seemed a good thing, better than holding onto the leader for another wonder later on.
After building a couple of libraries I started researching again. Techs weren't coming quickly enough from the Great Library. I learned Currency in 70AD and Philosophy in 150AD which put me into the Middle Ages - I'd received all other required Ancient techs from the Great Library by then.
And that's it for my Ancient Age. Status at 150AD:
The capital region is growing nicely. It has a number of ring 3 and ring 6 cities and is fending off American attacks from the south easily. I'm farming the Iroquois region, picking off towns as they grow. I have 33 horsemen at this date.
