Well, I got my victory in the end!
1910AD, so (assuming no blunder and it is an admissible game) not superb but not awful either. I'm happy, anyway.
It was quite an enthralling ride, and there were several points where I could have failed.
I set out for a win with the help of a PA right from the outset. I had added Roosevelt, Elizabeth and Frederick as potential allies. What I hadn't intended was to be situated right next to Stalin, and spend half the game looking warily at him, waiting for signs of his military being aimed in my direction, and pacifying him from time to time.
Oddly, I played a part in the elimination of both Liz and Fred - who I had added to the mixture myself! Liz was a weakling state that was about to be destroyed, so I joined in when I saw Roosevelt declare on her, as he was my main prospective ally and I wanted to get as many turns as possible in defensive pact or shared wars. Then Fred was getting blitzed by Stalin and I joined in at the point where everybody dogpiled him.
It did cross my mind that Stalin himself could make a very peculiar but possible choice of ally. I would provide the science and he could bring the production capability. I mulled the idea over for a while, keeping both him and Roosie pleased with me. Eventually I realised that Stalin was just too dangerous a leader to hitch myself to. Not so bad once you finally get the PA, but during the run-up to it, he is always attacking the wrong people, such as Churchill (large military and right next door to me!). So in the end I chose Roosevelt. He was much more stable, and getting the PA with him was a walk in the park, relatively speaking.
Churchill was on his way to becoming the world's largest power, and was busily dismantling Stalin's empire. Choosing my moment carefully, when Stalin's power was gone, I joined in the final city-grab and had a few last cities for myself. This took me up to about 10 cities, while Roosevelt had something like 12. This put us fractionally ahead of Churchill.
There were only 5 empires left in the world. Me+Roosie, Churchill, Joao, Justinian and Charlemagne. Liz, Fred, Mansa and now Stalin had all met untimely ends.
It was evidently going to be a space race, as opposed to a stroll. There were several of us all completing our Apollo programmes around the same time. I knew that we would win the tech race, though, so it wasn't going to be a worry.
But then the war came and anything could have happened!
I had been looking at Churchill and trying to gauge carefully whether he would take on myself + Roosie combined. But it wasn't him who declared on us. No, it was Charlemagne - much nearer to Roosevelt than myself - and never a friend to either of us - who suddenly started a war. I spent a couple of turns being unconcerned, and then saw a message about enemy units being sighted! After investigation, I realised I was in big trouble. A stack of 48 units had travelled across from South-east to me in the North-west. I had better units available (tanks, mech infs ... against his infantry, sams, cavalry - but stunningly no artillery!) but not enough of them. And another smaller stack was approaching.
It was touch and go, and I had to give up one outlying city in order to defend my capital, but I survived with Roosevelt's help. Possibly the key was losing the one city, as I could then direct Roosevelt to aim his attacks at that city, bringing all of his forces closer to me. Once there, he wiped up most of Charlemagne's stacks. I did the rest with my newly-built forces.
A couple of other points about this. The darned UN - which we built but then lost the vote to Churchill - had forced Free Speech on us, meaning I couldn't run Nationhood and draft units.
The other one is the monumental AI stupidity of trekking the length of the map with 50 units to attack me but not bringing any artillery. My artillery, plus some air units, really made the difference. I damaged his units to the point where he appeared to be backing them off to heal, but ran into Roosevelt's forces arriving.
That was the closest point to defeat that I think I came. If Churchill had decided to join in during that, the game would have been over. If Roosevelt had simply attacked Charlie's heartlands and not come over to help me, I might have been wiped. We were close to finishing the spaceship at this point, but I might not have made it to see the launch!
The war over, it went much easier, and the tech race had been won comfortably by my team. Always nice to get the internet, just to avoid someone spoiling the party by getting it themselves. Then first to fusion.
All the way through the alliance, it was evident that I was simply the researcher, and an occasional builder of ss parts. Roosevelt jumped in and built the rest without being asked to, which made a change.
Oh. Espionage! I got mauled by somebody (Churchill maybe, or Justinian or Charlie) just as we were starting to put the first parts on the spaceship. At that point I had only a couple of spies stationed, and I lost part after part to sabotage! My espionage ratings were very one-sided. I noticed Churchill had something like a 20,000 to 10,000 against me! The others were similar, if not quite so extreme. I built spies like crazy and it certainly dried up - whether due to these defenders or the steadily reducing esp points I don't know. It was very frustrating for a while.
But happy in the end. (Assuming it's accepted...)
