Wow... Some amazing games going on here!

How late did you actually build the Oracle, justjohn?
My initial plan was to REX peacefully with no barbs around. Expansive + Creative traits called for SE with those cheap granaries and libraries and that's exactly what I had in mind. No cottages this time! Also was hoping to find stone to build Mids for Repre.
3000BC:
Settled on the PH 1E to grab the corn. If I had been lucky enough to find those gems close by I would have went for them but now I had to leave that spot for the second city. Capital grew into a nice food + hammers city to build some shiny wonders for me, especially after horses and iron were found. Seeing the stone early locked my plans with Mids.
Initial techs were Agri -> The Wheel -> Pottery -> AH. Agri was a no-brainer with the corn around but after that I chose TW + Pottery over AH. Reason for this was that AH would have come too late to speed up second city by more than 1-2 turns. Now I could road the way to that nice gems-gold-wheat-stone site before settler was out and build granaries from the beginning instead of useless warriors.
Initial builds were worker -> warrior -> settler -> granary. Warrior was timed to get finished while growing to 2 pop and early Pottery allowed early granary. As there was no threat from barbs, warriors were useless until cities grew to happy cap. 2nd city was founded 2900bc at the mentioned Sampo-powered spot.
10AD:
As there was plenty of free land around with lots of flood plains, I spammed out settlers and workers until I decided that 14 is enough for BCs. 14th city was settled in 290BC. Each city started with granaries whipped at 2 pop and then continued with libraries to work 2 Repre-powered scientists quite early.
Instead of the usual Oracle-route I decided to totally skip religious crap and went for Writing -> Math -> Currency with Masonry somewhere to build Mids in the capital. Decided to skip Oracle and concentrate on REX + Mids instead (probably a mistake). Oracle didn't go unusually late so nothing like "Oracling Edu" seemed to be possible according to my game.

Besides Mids I've built also HG for +13 pop, GLib and NE in the capital this far.
Haven't had diplo problems, though Vicky and Alex have their hands full but I'm hoping they go for Wang who is outside the buddhist block with Peter. No wars up to 10AD (probably another mistake). Trades for some minor techs and gold have been good but nobody wants to give away stuff like Calendar or Construction yet. AIs are rather backwards so this really feels like a monarch or maybe even prince game to me.
Summary:
- 14 cities, 1 settler on the way.
- 84 pop.
- 16 workers to farm all those flood plains.
- 0 cottages, yay.
- 120 bpt @ 0% research from scientists (8 cities with 2 scientists, more coming soon). +82 gpt with GA on, probably around +20 gpt normally. Some 1200+ gold in bank. With 100% research would have around 300 bpt and -140 gpt without GA.
- Music, CS, Philo, MC, now researching Paper.
- Mids, HG, GLib, NE. Parthenon coming in 1 turn.
- Most cities have granary, library, courthouse and barracks. Now building forges to hammer-rich cities.
- Almost whole map explored.
