I surpassed all of my relatively modest goals for this game, already by the 500AD spoiler! At that point I was far behind in tech and power, and simply hoped to survive by diplomacy.
I had taken 4 barb cities in the west and settled two more there. I had only settled one city east of capitol. Mongols became vassal to Rome fairly quickly, and my having joined Romes war (in spirit), Ghengis was quite irate at me. At least as a vassal he can't act on that... but it seems as though his hatred of me affected Rome's attitude to me despite having good relations with Rome. Is attitude an average or something when there are vassals?
Anyhow, I did everything to get on Rome's good side. I used a spy to convert him to my civics, for example... but that only lasted about 10-20 turns. Otherwise, I used spies against Washington who was learning to dislike me since Rome was his worst enemy. I managed to steal HBR in about 1500AD (already obsolete). Otherwise, I kept stealing his treasury, which kept my research rates high. So high, that by the 1500AD's I was matching the AI rates and even almost matched Rome and the other warring nations in tech. Rome had taken most of Washingtons best cities, but had reached stalemate near Washington and started losing them to cultural pressure. Meanwhile, I ended up taking two Roman cities with American names by culture! Yeehaa - conquering by culture.
Wang Kong takes advantage of Rome's bridge-too-far escapade, and DOW's him and starts rolling up Mongol and Roman cities (as far as Antium). Suvreyaman was alsmost a non-factor in this game, despite being ahead of me in score.
Live by the sword... die by the sword. Meanwhile, in the west, my furthest south city (Uzbek) which has my FP and Hermitage and two cathedrals and every culture building I can build while running as many artists as possible and building only culture... revolts to Mali (again and again while losing population until finally they become Malinese). Unbelievable culture pressure from Mali... and the closest Mali cities were not even his legendary cities!
Never had time to rebuild an FP nor Hermitage (nor had time to lose 2 more cities to Mali by culture -- but almost).
Well... it was a good learning experience and I did a lot better than I expected. I think if we play enough deity games like this one, I can actually entertain thoughts of some day winning one of them. Certainly don't need to quake with fear at the thought of playing this level anymore. Its quite possible to keep up in the mid-game, and if you don't give up too much ground early on leaves you with good chance at victory. I didn't do that, though.
I finished ahead of Ghengis and Washington and even Rome. I was too timid with war, but my hopelessly backwards military tech made that probably the wisest survival strategy in this game. But next time I would do things differently
