There's plenty of time left yet for this contest, but we might as well get the Spoiler out!

How did your game end? Was it a fight to the very end, or were you able to assert your Russia earlier?
Shame on me, I should have won this one. I was early & late on my pre-build for the UN and ended up moving my palace and having to start over just before I traded for Fission.

One thing I noticed throughout the game was that I could almost catch all the AIs from a tech perspective at the beginning of each age. When I reached the new age, I would generally be only one or two techs down (or was able to get there with the free tech).
1080 AD: America attacks Ottomans activating my MPP and I take their 3 towns on my island, triggering my golden age, and spoiling my rep in the process.
Note to self, avoid MPPs unless I plan a long term military campaign and do not need trade buddies.
Later Scandinavia declares and takes an undefended town with super hatchet guys, I take the opportunity to drive them off of my continent with my Cossacks.
1285 AD: Ottomans declare on me and I bring everyone else in with alliances or MPP, finally get coal from Germany for an arm and a leg (gems & 48 gpt).
Build lots of Bombers as that allows me to sink any transport / Battleship pairs that try to land. Build a few privateers to allow me to run out to where the carriers are and do the same to them with my bombers.
Enter the Modern Age with a monopoly on Computers. Try to gain enough goal to purchase next tech, but find that only resolving a later war with Scandinavia (they declared, I MPP England and America, Scandinavia align with Ottomans) allows me to leverage the goal. I take Oslo, and gain Richmond and Jong something for peace.
Start researching techs again.
Scandinavia declares again and before I do anything, somehow I activate the MPP with Ottomans (probably an artillery defending a new town in Scandinavian lands). I bring English in again. Elizabeth is Gracious when she unloads on my continent and next to Oslo. I surround her with Mech Infantry and wait for her to attack (she does, and I destroy all her landed troups, battleships and transports in range).
Ottomans are not willing to negotiate peace but send no troops or navy to attack. Gain peace with Scandinavia, and lose all of my Scandinavian holdings to either England (Richmond) or Scandinavia after Oslo flips.
1956 AD: We discover a new source of coal (ha! ha! ha! - I'm fully railed).
1964 AD: Researching Laser with three parts to be completed in the next 4 turns when the Ottomans launch (until I checked after the game, I thought the English had launched). I could have switched to Communism (which I was in in an earlier war), but I felt the lost time would have cost me the game, and I expected the Ottomans to be willing to negotiate after their initial assault was sunk (literally). The perpetual war produced enough war weariness in Democracy to cut my research by about 30-40%. I probably would have been better off by switching to Communism.
Cossacks were a great help when the Americans. Later the Scandinavians declared war, allowing me to push them off my continent. After those wars when I had tanks and infantry, the Cossacks, and MDIs were disbanded to help build banks and stock exchanges. Midway through the Industrial Ages, I learned that I could get techs faster by buying them but waited too late to switch to Democracy (or Republic).
I must say that this was the most enjoyable game I have ever played in which I lost. I managed to catch England in the tech race and was one down on the Ottomans, but then they left me behind, bringing Scandinavia with them. Pointwise, I finished third.
