It looks like the barbarians are a bigger problem than the Iroquois. Nothing wrong with some cannon fodder to promote our troops to elite though. I'd like to expend our efforts towards increasing the size of our empire.
Currency due in 5 (losing 8 gold/turn). Once this comes in, I will switch to literature. Ollantaytamba is our best producer, it gets switched to a palace as a Great Library prebuild.
As for troops, we have no specimens of our UU, so no way to start our Golden Age. Tiwanku is switched to a Chasqui Scout, due in 2 turns.
everything else looks good.
IBT:
Barbarians attack. We lose one horseman. They lose four, and we get an elite spearman at Juli. It looks like a barbarian uprising is in progress, so at least two civilizations are in the Middle Ages.
Corihuayrachina - Horseman -> Spearman (7 uncorrupted shields/turn).
Arequipa - Worker -> Temple.
Our palace gets some steps.
(1) 130BC
I kill another six barbarian horsemen and frag a camp.
Move two irrigating workers away from three barbarian horsemen who are right next to them.
IBT:
Three barbarian horsemen attack a spearman on a hill. That spearman is now elite

Cuzco - Settler -> Worker.
Tiwanaku - Chasqui -> Chasqui (I'm thinking Chasqui Scout army for pillaging).
(2) 110BC
I move some horsemen into Atico to heal and to await reinforcements (particularly the Chasqui, as I would like to get out Golden Age going).
One more barbarian horsie bites the dust. Our formerly irrigating workers can return to their irrigating.
Corihuayrachina has grown, and gets a scientist. This allows me to reduce science to 40% and still get Currency in three turns.
IBT:
Cuzco - Worker -> Settler.
Vitcos - Settler -> Catapult.
(3) 90BC
Frag another barbarian camp.
I send an elite horsie out of Atico to attack an Iroquois spearman/settler pair who appeared in the interturn. We get two slaves, but no leader.
Push luxuries to 20% as Machu Picchu grows to size 9. Leave the scientist at Corihuayrachina, he takes a turn off of our Currency research.
IBT:
Tiwanaku - Chasqui -> Chasqui
Corihuayrachina - Spearman -> Spearman
Huamanga - Catapult -> Catapult
Ica - Barracks -> Horseman
(4) 70BC
Chuito founded.
I fortify the new spearman in Corihuayrachina, as it needs the extra MP.
Currency due this turn, but I'm unable to lower the science slider.
IBT:
A barbarian horseman impales itself on our horseman in the mountains.
Currency comes in, Literature is selected. Due in
Andahuaylas - Spearman -> Spearman
(5) 50BC
Our first Chasqui Scout reaches Atico, and the advance on Iroquois lands can start next turn.
IBT:
Tiwanaku - Chasqui -> Marketplace
(6) 30BC
I get a third spearman into Machu Piccu, and can reduce luxuries to 10%.
Chuquiapo is founded.
Lose one elite horseman attacking an archer

A second elite kills him, but no leader.
Push science up a notch to get Literature a little quicker.
IBT:
A large contingent of Barbarian horsemen move towards Arequipa in the North.

Our Chasqui is in range of the redlined Iroquois archer, and attacks.
Income jumps from -8 to +21 gold per turn.
Science goes to 60% and literature is due next turn.

An Iroquois archer takes out a spearman covering our horseman stack without taking a scratch

Our injured archer in the mountains defeats three barbarian horsemen before succumbing. Five more move next to Nasca.

Cuzco - Worker -> Settler
Machu Picchu - Hanging Gardens -> Marketplace
Corihuayrachina - Spearman -> Spearman
Huamanga - Catapult -> Catapult
Oil Springs suffers from disease, and population drops to 1.

Portugal completes the Colossus.
(9) 30AD
Attack two wandering Iroquois archers with elite horsemen. We win both battles, but again, no leaders.
We attack Allegheny. They lose three spearman and an archer. We lose one horseman and take the city. I move all available troops in to quell resistance.
Tamboccocha is founded.
Drop science to 40% and drop Luxuries to 0% (Due to Hanging Gardens). Code of Laws is still due in 4 turns, and we are making 66 gold/turn.
IBT:
Resistance in Allegheny is quelled.
Somehow the Iroquois sneaked a settler pair past our troops, and Oka appears. Oh well, another target.
(10) 50AD
We don't have enough troops to mount an attack on Oka, so I place the wounded into Niagara Falls to heal. There are a number of troops in Allegheny, many of which are healing. Lee can move those troops out is he considers it too much of a flip risk.
Switch Ollantaytambo to Great Library, due in 15. This will give us immediate tech catch-up when we meet the rest of the civs.
Oka is a blight on "our" landscape and must be destroyed...
