Spoiler thread up at last. First time in a long while I have actually finished my game early enough to post.
Settled on the marble for the extra hammers -- first worker finished amazingly fast, then warriors for exploration. AH first for the pigs, then BW. No copper visible, of course.
I had found the flood plains to the west, so went Wheel -> Fishing -> Pottery so I could build a mega-commerce city. Hamburg went on the desert hill by the pigs and paid for my early empire. Munich went to the east on a plains hill with more pigs and clams. Cologne went north for the silver.
I did not get Stonehenge, too busy expanding. But having seen how much land was out there, Berlin built the Great Wall, finishing it the same turn I saw the first barb warrior. This was a key move, allowing me to avoid spending hammers on units. If anyone did not build it, I will be interested to hear how much barb trouble they had.
I met Catherine to the west, and got a lucky break a few turns later when I founded Judaism and she converted the next turn. I quickly realized she was on an island, and resolved to keep her off the mainland. This would lead to two short wars later, as I declared on her and razed her city each time she tried to grab the iron site on the edge of the jungle, south of her island. Relations were badly damaged, of course, but the mainland was mine. And Catherine was too weak to challenge me once I had settled the coastal areas she could easily reach.
I built the Oracle early and took Metal Casting for cheap industrious forges. I almost certainly could have gotten a more advanced tech, but without knowledge of other civs I did not want to take the risk. Also, I really like early MC when I am industrious for the hammer and happiness boost. And the silver was the only early happiness I had, other than religion.
By 500 AD, I had 12 cities and was continuing to expand rapidly. I had built 7 wonders including Pyramids, Hanging Gardens, and (475 AD) Apostolic Palace. I got an early Great Spy from the Great Wall, which I settled -- knowing everything Catherine was doing was a useful advantage. Despite the Temple of Artemis I got two merchants for GPs #2 and #3. Prophets had been most likely, and I could really have used the shrine cash as I had been spreading Judaism widely to take advantage of the hammer bonuses from the AP.
I had not met anyone but Catherine at 500 AD, but I had not made any effort to push for Optics. As is probably obvious, I had not decided on a victory condition at this point. I was just focusing on growing into all the available land, and having a ton of fun with an almost pure builder game.

Tons of land, zero barb issues due to the Great Wall, and industrious with marble. Life was good for the German people.
