Round 6: to 1200 AD
Build, war, build. That about sums it up. It also tells you what we're in for come the next round.
I started by making a wee diversion on the tech path. It was only going to take one turn, a trade for it would have been very lopsided, and it would allow me to build some more science multipliers in addition to libraries:
Then I went back on the path to Banking. I immediately changed build orders in Frankfurt to a Confucian monastery. I later spread Buddhism there and built a Buddhist monastery as well. Meanwhile, the Heroic Epic was built in Cologne.
I tinkered with the slider, but I would have had to set it at 100% research to make a significant difference and would have had a large deficit that would eat through my gold in no time. So I left it at 0% the whole round.
Meanwhile, my next wonder finished in Hamburg:
That was handy. I did a tour of my cities and was able to increase the number of scientists in a couple of them while still keeping growth at a reasonable level (+2 food per turn in almost all my cities). As has been pointed out, I'd delayed some vital infrastructure--granaries in particular--in favour of military, so the pop boost helped offset that opportunity cost somewhat.
Kublai, mired in his war with Monty, also came by for a visit:
Ah...no, you're on your own, big guy. I'm keeping Monty as happy with my as I can until I'm ready to take him down. You, on the other hand, are expendable. Later in the round, Monty captured one of Kublai's cities and then they made peace. They're now pleased with each other again, but Monty has declaring war on Kublai as an available option in the diplomacy screen. I'm pretty far ahead of Monty in tech and cash, so later on, I should be able to bribe him into attacking if I want.
But I had a war of my own to finish.
He was just about to plunk down another city just south of Pasargadae (there was a Settler and an Archer accompanying the Spearman you can see to the left in that screenshot). I hemmed and hawed and decided that I didn't want to waste time bombarding and capturing three cities instead of two, so I took them down before moving on to besiege Arbela. And, of course, I got a free Worker for my trouble!
I also got some more Great People.
I got three Great Scientists this round--two from Frankfurt and one from Hamburg. Two settled in Frankfurt for additional research. I regarded the one from Hamburg as a bit of a freebie since I was expecting a Great Engineer whom I would have saved for a worthwhile wonder. So instead of settling him, I used him to acquire Philosophy, especially since Taoism had not been founded yet and I wanted a leg up on the Liberalism race. Munich became the holy city. Unfortunately, the free missionary failed in his attempt to spread Taoism to Frankfurt so I could build another monastery. I'll have to try again later, and with Christianity as well.
You can weigh in on whether burning a GS for a tech is the best use of him in the specialist economy or not. I suppose not, since it's all about specialists, and I just burned one instead of making use of him for the rest of the game. But as I said, I wanted a leg up on the Liberalism race. Eggman had agreed with me that my research was progressing more slowly than expected, and I was making a research diversion to Banking (which I usually don't research until AFTER Liberalism). So, as with several things in Civ, it was a trade-off.
Shortly thereafter, Herr Cyrus was finally
kaput:
Yes! The southern half of the continent is now MINE. Very satisfying.
Just a few turns after that, a very significant technology was discovered, one I'd been working towards in order to further boost the specialist economy:
With everything now in place, I made a civics change:
Representation for the continued research boost per specialist, Bureaucracy for the boost in the capital, Caste System for the unlimited scientists, Mercantilism for the free specialist, and Organized Religion for the help infrastructure buildings.
While I lost several GPT from the lack of foreign trade routes, the multiple scientists I'm now running in several cities has been a huge boost to research, especially as the captured Persian cities become productive in that regard. I'm being careful to ensoure the cities can still grow. But WOW--4-5 scientists in several cities is making a big, BIG difference. It's obvious that those two civics really unleash the power of the specialist economy once you have enough farms in place.
I'm teetering on a deficit at 0% on the slider, but I'm managing to stay afloat even without any merchant specialists. I'm building some markets and courthouses to help with that. My large standing army probably isn't helping, so I really should get some use out of them shortly.
I played a few more turns to get things settled out (including researching calendar just to get Munich's bananas plantationed). Here's the map at 1200 AD:
And since I'm getting all antsy to go to war again, a look at the power grid:
I considered diverting research again, from Education towards Engineering, in order to gain the road bonus as well as Pikemen before attacking Kublai. But then I checked the resource screen and saw that poor Kublai apparently doesn't have any horses!
No Keshiks for you! says the Civ nazi!

So instead, I'll stay on the Liberalism track...
But what should the free tech be? Printing Press is not going to be very useful this time, with no cottages to speak of. If I want Astronomy, I'll have to make a detour to Optics. That may not be a bad idea, so I can get a couple of Caravels out to find the remaining civs and potentially circumnavigate the world. It's only three turns. Sounds like a plan.
Since I'm still building some infrastructure, I think it may make sense to bribe Monty to attack Kublai. This would divert some of Kublai's forces away from his borders with me, as well as potentially weakening him. The problem might be that Monty would be TOO successful, but then again, that would only spread his forces more thinly when I do take him on.
I also have a bit of empty space south of Tarsus where I really should put another city to grab the wheat and the copper. Hmm, yes, I razed one that Cyrus put there in the first war, and now I think I probably should have kept it. Live and learn. I also should eventually found a coastal city south of Pasargadae just to snag that whale tile. Kublai has a galley with an Archer and a Settler just starting to travel down my east coast, so he may do it for me.
Here's the saved game, and I look forward to your thoughts.
