925BC
Here's the situation when I opened the game at 925BC:
Zulu have Math, Iro have Map Making. We don't really need Map Making but Mathematics would be useful for catapaults. We have 151g and 21gpt. Monte is not part of the negotiations as I don't want to risk our reputation so I'll start with Zulu. My objective here is to get Math from Zulu first for cash and credit, then Map Making from Hiawatha for Math and cash, then sell Map Making to Zulu for cash and whatever else he'll offer.
First I check the luxury slider and make sure our net as reported in the diplo screen will be a high as possible for trading purposes (It can always be turned back up when the dealin's done. Helps my moood to listen to Willie sing "The Gambler" when trading).
Then I buy Math for 131g and 3 gpt from Zulu. Then trade Monte Math and 3g+1gpt for Map Making. Then sell Map making back to Zulu for 188g.
The net result is that I pay 30g (4gpt for twenty turns less the extra fifty picked up when I resold Map Making) for two techs. We are back to parity with the Inca (our long term problem) and have a nice treasury.
Now back to building for war.
Through the turn built a bunch of horses and parked them on the border with Aztecs. Also built two catapults and a galley that was sunk by a barb.
It is now 750BC. I have whipped a temple in Palenque by first whipping a settler for one citizen and then the temple for two more. When the border expands the town can go fishing as well as farming, I think, but it will have another hill anyway for some more shields. The town is food rich but shield poor for either settler or worker farming right now and it does need a granary for either.
The settler from Palenque is heading for the corner with the cows with a trailing warrior escort.
When Chichen finishes its spear start the ToZ while the workers chop the forest to help the settler build at Copan. Use the settler to re-settle
on top of the Aztec iron after we burn Tlatlcoco. Switch back to a horsemen when the chop is done.
We have met the Americans off in the far west.
Time for war

Millie the MilAd says we are strong compared to Monte.
Campaign plan:
Strike for the heart. Burn Tlatlcoco, then move on the capitol. The other towns are small and will autoraze when captured. We might consider taking the capitol then waiting for them to grow to two before capture so we won't have to resettle them. Now that I look at the map again I realize his terrain outside of Teno is even worse than ours so the growth is unlikely and it will be whipped to produce spears anyway.
Keep the forces together! Don't chase strays.
There are two Aztec warriors in the swamps outside Chichen.
It is likely that Monte will invite the Zulu to the ball once you have declared on Aztecs (from outside their borders) so when the reel is called ask Shaka if he would care to dance.
Have fun TC!
