Sub-200 is indeed possible. Finished on 195. It ain't easy.
I settled in the common places but did quite a lot of things differently. The big thing about this game was that the AIs had decent GPT. If that's the case and the player also has GPT, it's possible to manage the AIs' finances by borrowing. The idea is to repeatedly borrow from AIs that reach 200
before they can spend it, then lend back anything they need to cover the costs of an RA. This permitted me to finance no fewer than 12 RAs, at the cost of having to hard build almost everything until the very late game.
The correct opening purchase is indeed glory's Worker/Pathfinder buy. That permits getting three upgraded Composite Bowmen very quickly. One stays home to guard improvements, pick off easy barb camps and intimidate local city-states. The other two run around the map meeting, extorting, and playing Team America: World Police on the barb camp quests.
My start was a little unusual: Pathfinder -> Worker -> Pyramids -> Great Library -> National College, then going for Settlers and infrastructure. Mining -> Masonry were the initial techs, and I went Tradition -> Liberty -> fill Tradition tree. I used the
from tribute to buy a Settler around turn 20, and settled it on the south Desert city site. It's the better of the two Desert sites due to all the river Hills, you can chop a Library for a two-city NC start, and getting the city planted early sets it up well to get Petra done before any AI can around turn 80.
Team America was a little
too successful at befriending Culturals, so I accidentally ended up with an extra policy before Rationalism. I spent that on Citizenship, as double speed Workers aren't a bad problem to have. I considered Patronage and Commerce, but discarded both options. Big Ben would have been nice for labs, but 15% is a pretty weak bonus. Patronage would have saved some
, but not enough to compete with speedy Workers.
I was a touch slower than glory's times; I hit Education on 86 and Scientific Theory on 135. I saved Oxford for Nanotech and used the Rationalism finisher on Radio, so I was in the late 140s by the time Modern popped. Plastics hit on 160 IIRC, with the Labs more or less in by 170. I bulbed somewhat aggressively to open Rocketry, hard built Apollo and Hubble in the capital (which permitted popping an extra GS the turn before Hubble finished) and produced parts elsewhere. I was able to GE the last part and even had enough
to throw a GE at the slowest remaining part.
The biggest issue was that I was frantically trying to stay ahead of
throughout the middle of the game. I had to go Acoustics immediately after Education to avoid another wasted policy, and I ended up with a gigantic city-state
vacuum which forced aggressive borrowing just to stay above water. Then Notre Dame finally hit and I was able to save up for RAs between 115 and 130. The only other thing that really went 'wrong' was that one of the AIs screwed me out of Temple of Artemis around turn 40.
Another thing I did that no one has yet suggested was to take Divine Inspiration, which seems like a no-brainer on a lower difficulty where we wonder whore. It would have been even more fantastic if Egypt hadn't nailed my Petra city with a Prophet around turn 130, costing me at least 15
per turn between DF and the Wonders. I probably should have dropped an Inquisitor, but it didn't occur to me until too late. It didn't really matter, though; I couldn't have bought another Scientist or Engineer with the lost
.
I think I built Wonders in three different places. I took GL, HG, Oracle, Borobodur, PT, Notre Dame and Hubble in the capital. The second city built Petra, Hagia and Pisa. My third city built Taj. Caravans stayed internal for
until parts time, when I switched to
. I had more or less full map coverage of religion due to Boro and the Hagia GP until Egypt had a couple of Prophets start working overtime.
Last trick: getting to Printing Press and queuing up World's Fair is fantastic for getting DoFs. I think I went from one to six within ten turns. It's worth delaying Astronomy for if you are forced up through Acoustics due to SPs.
Long story short: map is OP, RAs are still OP even on lower difficulties, and the totally random AI cash lotto coupled with the new random willingness to DoF completely determines how fast you can finish.
