this is an "got it" and kind of PPP post...
Maybe first I will try to do a bit review of the game as I see it right now.
I think we did great job with our wars and secured deciding number of cities from AI's (16). We are not that good off in the way for next great person, since we want to get Great Merchant and each city I checked had already big pollution (even Frankfurt) which makes getting GM as next GP risky, thus we should have in mind that we actually could need buildup GM points for 2 consecutive great persons.
(frankfurt has already over 300 nonGM GPP - it's 25% of GPP for next GP)
In the beforementioned problems I agree with switching into Caste. Berlin switched to growth and Frankfurt employs Merchants.
Victoria is 1T from Gunpowder (means muskets), HRE is working on Chemistry (11T).
From the look at the map I absolutely don't know why we would attack Victoria since her only city in reach is York and is pressed from Ankara and Konya and we would have big troubles to hold those city against the culture pressure from Sully.
I am strongly against attacking Victoria. I could see us taking Bursa and Konya/Ankara from Sully instead (Ankara has Versailles) (but strongly complicates our tech trade situation with HRE and Vicky being WFYABTA).
But in Bursa Sully has around 15 troops and could be hit 1st turn of war.
But I would prefer no warring at all.
I don't understand why we build non jewish religious buildings and why we don't build jewish temples everywhere.
I would try to finish spreading jewish into our last 2 cities that don't have it.
If someone knows better then me (and I am not sure really) if we can change religion through diplomacy of our Vassals, maybe it would be worth our time to spread jewish religion into our Vassals and convert them, since our diplo situation now is averaged.
I see Rheims as best candidate for Forbidden palace (after Jewish temple and forge) and we will need it due to our variant (corps)
considering builds... generally.
Every city should have granary, courthouse, forge, jewish temple, maybe theatre and if it has everything should build wealth to push up slider.
thus cities having 0 hammers invested into builds that are not anything mentioned before will be switched.
There is exception with Jewish missionaries, where I would slot in 2 mishs, if we agree to spread to vassals, then of course more eventually. Our HE city is probably best candidate :-D
As for techs I would continue towards Refrigeration (better said scimeth->biology->medicine, since we need astro+physics+electrics too for refr, but there should be some tech trades for it involved imo).
As for the workers I would continue with the work of my ancestors. I think Yakutsk needs farms from irrigation, but i have a feeling we are already preparing irrigations there with those 2 workers.
I can't switch back to bureau since it would cost us 2 turns of anarchy and maybe even wouldn't be worth it.
So basically that is my feelings...
