Another run for the Rus UHV - inspired by Orbii's game - going for the 3rd UHV (4 fur and 3 salt) before the Russians spawn in turn 67.
General strategy:
Settled Lubny, Oskol and Minsk and set tech-slider to 0% getting a lot of gold for hurrying military units (with citizenship). Lubny build Barracks, Druzhina, Arean and missionaries, Oskol Barracks and Druzhina and Arena, Minsk Workers and Settlers.
Result:
Sadly missed UHV 1 this time by 3 points, but could be done with better play (and a bit more luck, event destroyed the pastures in Minsk).
UHV 2 was done in 1120 AD long before the deadline. Got totally swarmed by barbarian Horse Archers, Oghuz and some Keshiks this time. Waaay more then before. Mongols declared war on sight, but did not really attack.
UHV 3 I missed by some turns. Workers still bulding the last fur and salt improvements. Settling Novgorod/Spas-na-Kholmu instead of Oskul is probably better.
Observations:
The Unique Building is too insignificant, I think. It's only +1 commerce even with merchant trade in popolus cities. You can invest your hammers better. -> I like the theme of the UB, but it needs a better bonus +100 % trade (at least), free merchant, free food or hammers, automatic spread of your state religion...something. ;-)
UHV 2:
Seems a bit luck dependent. If they don't come in hordes it may be impossible to find enough barbs. And if they swarm you, you have to kill them anyways. So perhaps there is something more interesting... (not sure what).
UHV 3:
Getting 200 gold through trade is trivial - it just happens. ;-)
The 4th fur is hard, you have to go really far to the east or to Scandinavia (or trade it with the Norse
if they trade).
Minsk (in Ruthenia) should not defect to the Russians (at least from the perspective of a Rus game). Make them spawn only in Russia or east of Russia, not in Ruthenia. If the Russians are too weak then, give them another settler or more units.
Will give it another try to go for the UHV before the Russians spawn and then try in another game the long run with conquering them for UHV3.
I really like the Rus scenario for UHV1 and 3 and the possibility to do them in various ways - so thanks againto Leoreth for his superb work.
