At the end of the last segment I was puzzling over my tech path. In the end, as my failure cash deficit research would only carry me so far, I decide to rush for a safe but boring Lib-Nationalism, attempt the Taj, and tech my way to Optics>Astronomy, aided by the GA and a Printing Press bulb along the way.
Naturally I revolt to Free Religion ASAP, might as well benefit from my godlessness.
In 1250, My caravels reveal most of the other civs - Willem and Isabella (both Christian), Huayna (Confucian) and Kublai (Jewish). Kublai has 15 cities and Huayna as a willing subject. It would seem that I was wise to err on the side of caution with my Lib plan, as Willem has Lib by the time I meet him.
All the warring and religious hostility has lead to a manageable tech situation, though. There are still the Hindu and Buddhist nations to reveal themselves...
Turns out to be Monty and Brennus, who are at war. There is plenty of hate so trade possibilities are limited if I don't want to become everyone's worst enemy. Oddly enough Monty is not Brennus' worst enemy, Isabella is, so I get some trades with featherhead.
Plenty of careful tech trading ensues, making sure not to ruffle any feathers (Monty's or otherwise) by trading with worst enemies.
Much needed resource trades raise my happy and health caps, at last.
Izzy enters WHEOOHRN. She has a worst enemy and is annoyed with three other civs besides. Is she going to attack me at cautious? Probably.
Next thing you know, the Mongols are planning war too. Stressful.
Isabella DoWs Brennus, he of the four cities who is already at war with the Aztecs. Defying her stupid AP attack resolutions starves my single Christian city to death.
Monty gets peace with Brennus, and moves his big stack to the North...(this screenshot is especially for that guy who thinks the AI never builds mounted units)
and DoWs KK. This should be a good fight.
Huayna breaks away from KK soon after, and surprisingly I rise to number one in score. Don't think I've ever done that peacefully on immortal before, but then how often do you peacefully get fourteen cities on a standard map?
The Aztec-Mongol war ends with victory for Monty after he takes back both his own cities (lost in an earlier war before I met them) and adds one of KK's for good measure. KK peaces out but Monty continues to fight HC for ages.
It's time for me to make a move. Isabella is one of the most irritating AIs in Civ, so killing her is always a relief. Thanks to Willem for providing a nice launch point.
This Cossack land assault is augmented with a naval invasion to the north, and initial progress is decent.
Izzy tries an ambitious but rather futile counter-invasion with medieval units...
My initial attack is slowed down by Izzy's acquisition of rifling (probably traded with Will for Medicine), but I get there in the end.
While I was busy with that, Kublai reopened hostilities with Monty in 1795. Monty gets the better of it through sheer numbers. KK has infantry and cannon, Monty hasn't discovered steel or rifling yet, but his cuirassiers and grenadiers are so numerous that KK is getting mauled.
For a while it looks like might overrun Mongolia completely and vassalise Kublai. That would be problematic. But then KK's cavalry steal back Kazan (lost in the last war) and the war ends with a treaty.
The next order of business is taking out crazy teching Willem. At the moment he's building the Electricity-Radio-Mass Media wonders for me, but he needs to be stopped soon before his teching goes too far. Fortunately I can outproduce him massively.
Attacking Will, the first step is to knock out his single oil city.
Then the rest will is just a grind to destroy all his infantry. Unable to build planes, tanks or warships and defenceless against my bombers for a few turns until he gets to rocketry, all he can do is delay the inevitable. Everything goes as planned.
Before I can finish Will, Monty DoWs Brennus. Naturally, KK takes Brennus as a vassal, and another big war is on. KK starts to get beaten soundly, so I use the just-captured UN to put a stop to it.
Willem gets eliminated. At this point I was in Police State pumping out units to win militarily, but then my diplo penalties with KK dropped to manageable levels. So I switched to his religion to get him to friendly, and that was all it took.
Thanks to the host, looking forward to another IU soon.
