So, I've been doing some thinking.
I have several targets in this game, which aren't compatible.
1) Machinery, for Cho-ko-nu.
2) Drama, for pavillion (best culture/hammer ratio in teh game, especially with the 25% bonus - with a religion in the city, that's a 2 turn expansion)
3) Engineering, for cheap castles, obviously after machinery (since machinery is a pre-req for engineering)
I have 3 paths to machinery, assuming I can trade for Metal Casting:
1) Tech there - it's 840 beakers, which is expensive, plus distracts me from going up the line to literature
2) Bulb with engineer - machinery is the first choice for a GE, so that will work - problem is, it will take 34 turns (unless I build HG or Pyramids, but those take a long time without stone)
3) Bulb with scientists. Machinery isnt' a high priority for a scientist - to get it, you need Aesthetics, Math, Calendar, Compass, Iron Working, and Sailing, and not have prereq's for philo (meditation and either CoL or drama). Since I want drama, this route means no monasteries. I can get two scientists with writing and the Glib gives me 2 more, plus a bonus for scientists, so that would be 14/turn.
My thinking is this:
Tech archery->pottery->writing->alphabet. Trade for MC from memphus and IW from the General - hopefully, I have iron. Assuming I do (which I need for my cho-ko-nu),
then aesthetics->lit, build the glib and national epic, and hope for either a engineer or 2 scientists.
hopefully trade for math and research sailing->calendar. Bulb either machinery (engineer) or compass->engineer. Finally, go back for monarchy.
City builds:
A few archers in the Resort, while the cap chops a settler for the banana city and then a granary->lib->barracks->military.
Banana city gets bananas irrigated,
One worry is that Ronnie took a dive in GNP and a rise in manufacturing, plus someone has a spike in soldiers, so ronnie may be creating axemen. That would be bad luck for me, to have 2 opponents with copper in the fat cross (or maybe he's building chariots) - if it's axes, I probably have time to build archers - if it's chariots, I may not
