Stopped taking notes in the Middle ages when the game looked hopeless, from a game standpoint and also due to numerous crashes. The instructions for the various downloads (the all-in-one zip wouldn't expand on my system) rely on folder names for instructions. On the Mac (at least in os9), the name of the folders apparently truncated and I ended up putting resources at the root of Civolopedia folder when they needed to go deeper. Got help from the CFC forum and finally was able to play through the middle ages. Between that and a week's vacation forgive me for not splitting into the 4 spoiler threads, will try for just an overview here. Also, the crashes did result in me replaying quite a few turns. I tried not to take advantage, but don't know if that means my save is still eligible?
First, I had no Golden Age. I only engaged in one early war with England and couldn't manage the wonders. No opinion on usefulness of the UU, but I liked the graphic.
Early game I made several blunders. First, I found and blocked the lower of the 2 northern choke points, but not the other. By the time I discovered the 2nd, it was too late. England, and later Keltoi got some northern sites on (my) subcontinent.
France went far afield to settle Marseilles, to get horses and avoid the large jungle area. This put me on the defensive in terms of land grab; I started overextending myself and ended up wasting a lot of space right in the core. France settled a group of cities in my area and I tried pushing back with very aggressive settlements in hope of flips and also to get resources. The flips never worked and I had cities with France's borders on their doorsteps for almost the entire game. I spent too much time focusing on this. On the other hand, some land area was denied to them by my extending...
Did poorly with coastal cities, again wasting the available territory; was trying to take advantage of resources but ended up unbalanced. Only a couple of coastal cities and they were late and weak. Naval exploration was not much of an option and so I was late with contacts.
Needless to say I fell behind pretty solidly. I did wage an early war against England to get some of those cities in my north. I had inferior units even at that early point, but a proximity advantage. I did capture 2 cities, but lost one back. Keltoi also declared on England and I hoped to reap some spoils from that, but they advanced so quickly that even my horses couldn't keep up! England was reduced to a few cities and that was the end of war for Spain.
Thus began many centuries with Spain lagging the world in technology and development. I produced a goodly number of units even though they were obsolete to the point of ridiculousness; hoping that the numbers alone would discourage aggression from the other civs. Once those needs were fulfilled I built as much culture as I could, given my lack of techs. Other than that, quite a number of workers to at least get the land improvements and hopefully utilize Spain's commercial strength later.
Eventually (middle ages?) Zulu started taking out the Keltoi, and that finally turned into a dogpile. I did get some spoils from that, reducing my territory problems to France. France ran up a goodly streak of wonders and I didn't have much hope with such a strong nation impinging on my productive core and blocking my only avenue of expansion. Taking on the French, even with any conceivable alliance, was out of the question. Military victory seemed a deadend, and space race as well, as the tech situation looked hopeless. I continued to trade as much as possible, a lot of deals with the new-world civs so as not to feed my close rivals, but not exclusively; realizing that constant trade was the best way to keep everybody polite -- diplomacy seemed my only dim hope and I couldn't imagine getting Fission in time to have a chance at the UN. But I kept hope alive. Right of passage for everyone!
With Keltoi gone and England reduced to a colony, India and Zulu split the eastern half of our continent (oh yeah, ottomans went out early, before I even made contact. I think Zulu and India may have ganged up on them). I felt not much stronger than England, and in fact Liz was way ahead of me in Tech despite her devastated Civ.
Finally, Zulu declared war on France! My dream come true. France was powerful and had rails by now, but Zulu outmatched her in military and eventually French cities started to fall. I poached some good land and France falls back to a single city - Avignon. Whew! But now Zulu at my doorstep - yikes. I am still dragging the world in Tech.
Another bit of luck - India and Zulu get into it!! Talk about a clash of the Titans! Meanwhile in the new world, Aztecs take out America while Japan demolishes Iriquois. The India-Zulu battle gets into Tanks. I think I'm still around Gunpowder or so. Keep trading my butt off. I did get some good deals for extra Iron and with the fall of England I did manage to wrap up the world's Fur trade. By and by India crushes Zulu and... they're building the UN. I am soooo far behind....
Eventually, with France so far in the hole I am finally able to start trading some techs for techs. Got one deal with Zulu before they went out. My rep had been dinged early on when Iriquois lost a harbor or some such, so when Zulu went out it was no big deal to have trades outstanding. I was able to keep the AIs polite for the most part; though Japan and Aztecs required frequent gifting. Ghandi was nice too, until an Indian city flipped to me and I ended up abandoning it. oopsie! But since Ghandi was sure to be voting for himself... And around this point I start to have some glimmer of hope; I am starting to catch up on techs, India is the only Civ building the UN and they're building it in a backwater colony in the new world! Way to go Ghandi!

I am self-researching Industrial techs like mad.
By and by I get to the modern age and finally research Fission. A palace pre-build gets me to within 12 turns on the UN. Japan stops and starts the UN at least 3 times. Japan and Aztecs just couldn't share that whole big continent and they have a goodly war over there.
The turns tick by and I don't want to risk planting a spy on India, but I figure UN is building in a 1 shield per turn town. I think I'm gonna get this....
And.... YES! My first and only Great Wonder of the World!!
The build governors are not without a sense of irony
and with 90% of precincts counted we are predicting....
The final map
and the histogram
Somehow, Spain ends up the histographic winner too

I would never have imagined. Well, it was an ugly win but my 2nd Deity win, so I'll take it
I went on longer than I expected here. Nice game and very interesting to see all of the different outcomes. Looking forward to #21
