Finsihed up and submitted yesterday, so I'll post what I can remember.
Plan: Fastest reletively peaceful spaceship
Early game expansion:
I didn't actually start out with a specific goal other than REX & Tech, and sort of decided on SS when I met Mansa who is an excellent trading partner, and found gold. I settled 1NW to get some hills production in London, as well as lots of river tiles for cottaging. In test games, I was always very frustrated by either having to build obelisks to pop borders of new cities, or settle next to the resource I want even if its not an optimum location. So in this game I detoured to build SH after my second settler was finished with help of chopping. This slowed my REX significantly, so that I only had 3 good cities befor being blocked on the west by Mansa. Fortunately, I had copper and there was a barb city S of the mountains which I took from 2 barb archers without any casualties. That gave me room to the east (s of mtns) for another city. I had room for another coastal city SE of London, but didn't settle that until way later, like 1500AD or something.
Early game tech:
I went for BW first, then the wheel-pottery-writing-alpha route for early trading. Friendly relations and tech parity with Asoka/Mansa/Elizabeth, for a while, then as my cottages mature I pull away. However, there is someone far away who is ahead of me, at least to the religious techs. My tech lead gets me easily the GLib in London. Oracle gone before I even thought about going after it. I dind't get masonry till later so Pyramids also never tried. I forget if there were any other early wonders... they weren't any critical to my gameplan though. As often happens, London is my super science city, my super commerce city, my GPFarm, and one of my best production cities as well.

Not very good specialization (but heck, I only have 5 cities at 500AD and two of them are not very mature). Everything seems to be going very slowly, though.
I realize that I will need more land just to get enouggh cities for all the national wonders FP, Oxford, Wall St. and so on. So about 1000AD I attack Mansa with mace/cats. I take out his entire empire in fairly short order keeping most of his cities. Kumba Saleh becomes my best production city, and Timbuktu a good GPFarm - gives me the Pyramids and so I go to Repr. At this point I was determined for a nice peaceful space race... I had all the ingredients necessary... and then Asoka DOW's me from 'cautious' while I am 3 turns from Chemistry. Oh well, its a phony war until my mace have been healed and upgraded to grens... and then I decide to clear the continent, keeping the best and razing the rest. Grens against longbows = no challenge. I leave Asoka a small isalnd far away and give him peace for a world map.
Hatties borders give us contact... Wow, she's pretty advanced, ahead in more areas of the tech tree than I am. Need to contact other AI to get better tech trading soon, so I start working for compass, optics, etc. While mopping up Asoka and racing to Liberalism at the time. So I was trading techs to Hatty to gain those techs to open up Astro. Get astro as free tech for liberalism, and very soon I meet all AI and have tech superiority for rest of game. Very little trading possibiilties because I am too advanced.
However, all this warring has erroded my tech lead. Washington has a whole continent too, and is pulling ahead in tech, through a mutual love-fest with Hatty. Can't have that! Washington and Hatty have a defense pact when I get around to taking out Washington with 2 frigates and 4 galleons filled with Grens and cannon. I take Washington, New York, Chicago, and Atlanta, which is the better half of what he had. Hatty meanwhile didn't have a navy, so was not a worry for me. I tried to bribe HC to war, but couldn't, so I bribed him t oquit trading with Hatty instead. This paid off nicely, because when I gave peace to Washington after he got rifling for loads of cash (upgrade more of those cats to cannons!), Hatty DOW's HC. All Hatties troops are in the east and I raze her stone city and march towards Thebes. MISTAKE. I should have taken out some more coastal cities first. My stack breaks itself on the walls of Thebes (which is now garrisoned with lots of Rifles + cannons + cavalry) and just goes around pillaging while she mops it up. When she got cannons that really screwed me. I didn't reinforce because I was busy rebuilding/building economy + improving all the captured cities instead. Oh well. She still pays me for peace, so thats fine. And those cannon will be artillery soon anyhow.
Redcoats didn't come into play. I built maybe 4 of them all game, because rifling comes so soon after.
Whoa... looking where I am... I see that I've been going my usual domination-style game and forgotten about the SS! If I want to win by Dom, I just need to take the rest of Washington's empire which would be easy, and maybe one or two more from someone else. But to win a SS race, Hatty is still too strong, though the wars did slow her tech a LOT. She could steal a culture victory, too. So once I have artillery and a few SAM infantry, I take her 3rd culture city, and then to keep it from flipping back, had to take 2 more coastal cities. But culture pressure makes this untenebale unless I also take Thebes, with help from marines and tanks. And to get to Thebes I had to take her 4-wonder city too.
When Thebes falls (circa 1900AD) I am over the Dom limit! However, I quickly gift New York and Chicago to Washington, and hold at 63% of land area. So obviously I've made my choice not to go for my maximum possible score in this GOTM, since I am still many turns from being able to build an SS, but am determined to do so. So while I am teching beeline to fusion, I am building as many wonders as there are left, changing workshops to farms in all but a few cities, even farming over matured cottages in London. Milking this baby for all its worth, seeing my base score go up but my "score for winning this turn" going down.
I get future tech, then the last SS part is 2 turns away, I figure I can take out 4 more cities on the turn my SS is done before I launch thus maxing pop and land as much as possible. WRONG! Even though my advanced armor is in position, there is no LAUNCH button in Vanilla you dumbass

Game over. (Actually, when it said "Elizabeth won a SS victory" I was

that I let someone beat me while I was milking... until I remembered that I am playing as Elizabeth here

).
Man... vanilla Civ4 makes me feel like such a NOOB.

If it isn't GOTM, I always play BtS. Oh well... Monarch level is where I get challenged but can usually win (despite my very slow REX this time), so it was a fun game with lots of opportunities. Thanks staff for a very interesting game - I especially enjoyed the combination of AI we faced this time. My most warlike "peaceful SS victory" ever!
SS Victory for Elizabeth in 1992AD. Think I'll get a medal for that?
I'll see if I can edit in some screenshots and get more exact dates and tech order at a later time, in case anyone (besides me) is interested.
