Still with 200 years to prove that I won't lose a city, but I think I'll be OK.

Sputnik was launched in 1754AD, recorded as virtual (2/3) UHV in 1757AD.
(NB. I only actually built my 8th Siberian city (the one furthest in the East) after launching the Apollo Program.)
Founded four cities to start and then threw everything at Germany. Killed a Settler with escorts, took Berlin and Aarhus and got capitulation. Liberated Berlin and Aarhus to keep Germany from collapsing - it was touch and go for about 1000 years, but they actually hung in all the way (although they lost cities repeatedly to instability).
I always research Meditation first with Russia, because nobody else seems to want to learn this tech for themselves = cash inflow. Bought Fishing from Germany and Sailing from England whilst researching Meditation.
Once sailing is in, quickly whipped a Galley in Tallin and headed to make contact with Mali. Importantly picked up a Wine trade deal form Spain along the way, to appease the unhappy Russian citizens. Getting early contact with Mali is crucial if you want to try to build the Spinal Minaret, which I indeed wanted.
New requirement is for 7 (as opposed to 3) Siberian cities. Founded my first Siberian city pretty early to get the Stone online so that I could get in the race to build some key wonders. I lost Notre Dame to the Byzantines (even though Rhye tried to prevent this from occurring) but pegged the Spinal Minaret, Leaning Tower and University of Sankore.
Fairly straightforward from there, I got all my vassals after Germany peacefully - Inca, Dutch, Portugal and Mali in that order. Beelined for Rocketry whilst avoiding Scientific Method for as long as possible to get maximum return from my Religious wonders. Losing Monasteries took just less than 10% off my research pace.
Popped a Great Spy as my 2nd great person which was huge, allowing me to steal 3-4 techs from the Dutch. I then switched espionage to Turkey and stole Military Tradition and Military Science whilst I researched my way along the Assembly Line tech path. After those two techs I was the tech leader all around, so I switched espionage to France and eventually stole a
whole lot of gold, allowing me to run 100% Science for the remainder of the UHV race.
I plan to recreate the Soviet Union during the next 200 years. I've almost got it already, but need to declare war on Mongolia at some point as they are in the area that Vladivostok must surely be built. I've got Infantry, Artillery and Cossacks. They've still got Keshiks and Muskets.
