Long post, sorry...
Ok, I start by cleaning up the Viking army near Delft. I take a slight gamble with an axe vs wounded shock chariot (75% I think), and then another axe takes care of the sword. I move the spearman to the forest covering the two axes, and whip another spear in Delft. Ragnar's other stack is a horse archer, chariot, and spear...he suicides all 3 at terrible odds.
I reassign workers to build roads to the south for Utrecht, Rotterdam, and Amsterdam, which will crank out a lot of military in the following turns (I think I prefer grass forest to cottages in Nijmegen btw). Moving units is still painfully slow, I guess I'm glad this is epic.
I move the settler north to found Leiden. The silk-rice city would be very poor short term, we don't need blocking cities at war, and sharing the rice would hurt Nijmegen. On the other hand, Amsterdam has more food than it can use right now, and Leiden can get running quickly.
On the same tile as the missionary in that shot is a pretty nice French army. You can see it in NoChildren's save. But it had stopped moving south when it encountered roadless jungle and started retreating. Once I had completed the highway I told Nap to attack a specific city and he put the army back in play. Very good call bringing Nap into the war, I'm pretty surprised he was willing.
I'm surprised in part because nothing else related to tech trades goes right in my set. I switch to no religion on turn 2, but Charlie and Nap think too few know Construction still. I delay putting research in it as long as I can before it would start costing turns, but only Wang is willing to trade, and I already sold Monotheism for 100 gold.
But at least abandoning Hindu improves relations. Justinian and Ramesses eventually go to Pleased, and Charlie and Wang go to Cautious. Nap is still Pleased. It would've really hurt if someone else attacked us right now. I successfully begged Justinian for 60 gold (near the end of the set), and trade for dye, banana, and wheat with Ramesses and him. Note that we are still in OR, costing us something like 5gpt - I didn't think it was worth losing a turn of production to switch out. We can still build missionaries w/o monastaries at least.
As far as future relations with Ragnar go, I sour them a little with this decision...
I lose a CR2 axe and a shock axe in the siege. Fortunately, we get Construction and catapults 2 turns later. No phants, we need HR. I would suggest a new city 1 north of the ruins.
The turn before the battle, Judaism spread to his capital and he converted. A shame he didn't wait 2 more turns before declaring, so we could prevent that with missionaries. There's always the option of simply capturing Nidaros before we end the war...
This screenshot jumps ahead 5 turns or so. I saved and took a very long break after the completion of Construction. Up to this point I've been collecting forces for an attack on Uppsala, and I also have a secondary army forming in the west to take Etruscan (aka the sugar barb city) which is easier to move new troops to than the distant south.
I built the spy to check on the garrisons of Viking cities, and to find units heading north (Earlier I moved an axe into the forest near Delft to deny the defensive terrain to what I thought was a lone Viking axe. A horse archer came out of the fog of war causing us to lose the axe.) The spy revealed that nearly all Viking cities are defended by two level 3 axes and an archer - I unfortunately built a few more swords before I discovered this. I'm not used to AIs using so many axes for defense.
I don't think I'm able to take Ragnar's walled, axe-defended cities without cats, so I wait as they move south. Meanwhile Nap is moving a very nice army to take Uppsala himself. I'm worried he'll either take a city we want, or give Ragnar more promotions, so I send him to the landlocked city Jelling, which is still near enough to Ragnar's core to divert his troops. Maybe we also would've wanted that city, but we can't take everything ourselves. He does take it, and a couple Viking armies heading for us go on the counterattack.
The same turn as the French victory we finally get our Prophet. I intend to fortify him to save for Divine Right, but I misclick...
We get 15 gpt right away, and Hindu spreads to another city spontaneously in the next few turns. I've already been running scientists in Hague, and I assign some in Amsterdam now too. We are able to speed up gp generation significantly by using priests, but I think useful lightbulbs are better than a golden age or super specialist right now. When we get currency we can build a market to multiply the shrine (and the commerce at our low slider) and assign merchants.
Once I get a couple cats in position, I move to Uppsala. I don't wait to bombard the wall, and we lose 2 cats, a chariot, and an axe in the siege (pretty good exchange, imo).
A general is born, and I move him south. Instructor in Rotterdam or super-medic I think are our best choices. Ragnar suicides some mounted units on the spears in Uppsala on the counterattack. I intended to stop at turn 205, but we were 1 turn from Currency and an attack on Etruscan. Sorry but I'm selfish...
This battle does not go as well as Uppsala. We lose 3 cats and 2 swords, and the victorious units are badly wounded and vulnerable to counterattack.
Fortunately we can sue for peace if we wish. Nap ended the war the turn before.
I think it may still be worth it to try to take Nidaros. If we lose Etruscan to the archer, we can maybe retake it after promoting the swords. But I'm not sure.
Here's the military stats so far...
And the tech situation...
Justinian and Ramesses got Currency 1-2 turns before us unfortunately. So we are looking poor on the tech trade front, but our economy is in better shape now. We immediately got 20 extra commerce per turn from Currency, and we can build markets which are great at a low slider rate (unfortunately they're so damn expensive, maybe only worth it in Amsterdam and Hague). We also got the shrine, which incidentally lets us step up our gp generation.
