Based on that, I decided to hard-beeline alphabet. I research only mining to keep the worker busy, and then went writing (built a cheap library, and began running specialist) and Alpha. Alpha came in to T51, and I traded for BW, pott, and fish, and a few turns later for IW and sailing.
From the information on the research screen, I could tell that Oracle would likely be going a bit late, so I decided to go for it. Researched math first for the chop enhancement, and then CoL on the way to CS. The research was helped along by 4 scientist specialist. This btw means I also have an Academy up, which I forgot to mention.
I like that a lot, well played, sir !
I bet you had 5 cities when the Oracle came in.
My position is probably more advanced than yours but not by a lot. I have a higher research potential but the gold drain is also huge. From 1 AD, I'll need at least some 20 turns to get to a decent-to-good research rate.
I guess you'll need less time to push the research up but it's not clear you'll be able to research faster overall.
I think the main differences that play in my favour came from how we took down Hattie :
- running 4 scientists to my 2 decreased your production and delayed your attack on Hattie ;
- I had an early Chariot scouting Hattie's
2 cities and it spotted only 3 units (2 Archers, 1 WC) when I could start chopping into Swords, committing only a single city to it. I suspect you could scout her only a little later than me ;
- Hattie improved some outer seafoods, had a galley, but no settler loaded when I attacked ;
- she didn't settle the islands : I did so in her stead and that gives me a better GLH. I think those last two points are crucial.
Which means that, at 1 AD, I've got 3 island cities for trade routes.
Also the 4 extra cities matter... Not sure where those come from. I guess I whipped settlers more agressively than you did, including in Paris (so as to ensure some Western grabs on Freddie's peninsula). This is another area where the lost production from running 4 scientists may matter. For Paris' management, I mostly focused on not popping the GP there (because Oracle) but instead secured the first two GPs with Orleans (pure scientist production).
EDIT : emphasizing research for so long (900 BC) has costs of its own (production), which I could evade from much earlier (1880 BC).
Advantages for your game mostly come from the earlier Bureaucracy, extra production and earlier wonders (I got a 675 BC GLH, btw). Earlier HG for you doesn't matter much but I'm still quite far from the Great Library. That does matter for later bulbs.
