I thought about this one for a while. I decided to bank everything on getting the PA with Louis. So, I set almost all cities to wealth (since everything we wanted to research Louis already had) and removed our spaceship parts from the build queue. That way, we wouldn't waste any production if we were able to get the PA.
I also moved our Great Engineer to one of cities closer to the equator with the plan of rushing the Space Engineer.
1931AD: Oh no!
Kublai pops a Great Engineer! Crap. I presume that's it for the Space Elevator. Our new (and fourth and last) spy heads over to help sabotage production on one of Capac's spaceship parts. No PA offer from Louis.
1932: Well this changes everything!
Kublai used the Engineer to rush the UN! What the...? Okay, let's see how the relations look.
Well, well, well:
With Capac, we're at:
And with Kublai, Capac's at:
Capac actually likes us more than he likes Kublai! And we don't have any "trade relations" bonuses. But that fixable, if we had a tech or:
5000g is worth +3 in relations!
Still no PA with Louis.
Okay this is going to be tight, because I've found where Capac is building his Engine:
Seven more turns for his engine, and he's got two other builds too. This is going to be close. We should be able to interrupt his builds, but we can't risk our spies getting caught if we want him to vote for us.
1933: I just don't remember because next year...
1934: Yes!
A permanent alliance with Louis. Excellent! I ask him to start on Fission, then Fusion so we can get started with the Engine. (Oh, and I asked him for a Hit Wonder and his 2200+ gold too. I figured we'd put it to better use than he would.)
But also in 1934...a setback:
In the very year when we make our PA with Louis and can rush the Space Elevator with the Great Engineer saved for that purpose, Capac finishes the Elevator. Bastard!
So, I use the Engineer with our other great person (a scientist?) to start a golden age. Intense....
1935: First election for UN Secretary General and...
1936: And the results...
Yes! Even Capac votes for us! I lose the majority of my fingernails on these turns.
1937: Kublai offers us Refrigeration and 590g for Fiber Optics. Done! Groan, Capac finishes his Life Support. I gave up on blocking his Life Support (which will finish sooner than his Engine) and put all 4 spies in Corihuaysomethingay to stop his engine. But for the love of humanity, give us the option of calling for a diplo victory vote!!!
1938: Fusion is in. With engineers and starvation, I can get the Engine done in 8T in Moscow. Capac is just one turn away from completing his Engine.. But, I can't use the spies because if they get caught, he'll get mad.
Crisis! I can't block his Engine since the vote doesn't come up this turn. I decide that since he has one more part, I'm going to gamble that they will not finish on the same turn. I keep one spy here and send out the other 3 to nearby cities hoping to find his Stasis Chamber city.
1939:
Finally, the vote is called. But Capac finishes his Engine. And in his capital:
Three turns to go until his Stasis Chamber finishes! But, I can get all 4 spies to the city. My fingers are gnawn away to knuckle bones.
Oh please please please
1940: And
and!
...sorry, I have to run. I'll finish the report soon.
