MarbleStart Turnset T40-90
I feel like posting every. sinlgle. turn. is a bit tedious for you and me, so I'm going a little higher level. I'll cover what happened and any interesting tactics.
(update in progress...check back)
Hamburg: pretty uneventful. I took 5 Q's there around
T51. I only needed 3, but I would never go without at least 4.
Random Event (first time ever!)
My 4xp Q got a free
Leadership promo!

How fun. (That's double experience from now on)
On the same turn, Berlin got a free road+cows pasture.
Hot tip: Now that all Q's were used to secure 1st capture. As painful as it is, you need to send one Q to the post-Joao AI targets to look for horses and copper. So that means
Washington and DeGaulle (it's time to steal from DeGaulle again anyway).
BronzeWorking.
Willy has
Copper, but no BW yet.
Vicky (far East) has it too.
One NE of Fred, and
Joao's capital has one
T58 Joao -> Slavery

Yikes. Now I need extra Q's for Joao in case he whips archers.
Adapt Plans:
Joao's 2nd, Oporto, will be easier and require fewer Q's. Also the Washington Q (see above) can join in at
Oporto, so it's next.
Meanwhile, denying DG's horse...
Hot Tip:
See the pasture? You can spot those horses even before the pasture. When DG learned AnimalHusbandry, that grass tile gets a suspicious hammer (same with copper or iron). Since he didn't take Slavery (BW), it's horses. And, of course, now that it's pastured, it's obviously horses.
Hot Tip:
My Q arrived earlier than shown in the screenshot. I could have DoW'd and scared the worker away before ever getting the pasture. But since he
doesn't have slavery (can't whip a chariot), I wait because:
a) I get to capture the worker for my purposes
b) loss of worker prevents DG from re-pasturing soon
c) I get pillage gold for the pasture
d) Instead of leaving a pasture that only needs a couple turns to complete. It has to be re-done from start (only 6 turns for the AI--12 turns for me)
T64: Oporto captured
(screenshot showing
Lisbon plan)
This shows some typical war planning for me. I don't want to pay for Q's that trickle out, waiting for a stack large enough for Lisbon, so I plan carefully to
chop 60h in Cuzco. The chop must come after a Q is built so you get a 2nd and 3rd consecutively. Those all wait in Cuzco (so they
don't pay supply costs) until the time to hit Lisbon. This can easily be foreseen as T70 DoW, T71 capture.
So all
3 Q's move out T65 for Oporto.
The Hamburg Q also joins the attack. Note, the green path swings down south to scare off any workers chopping Lisbon's east side.
The DeGaulle Q (after pillaging the Horses) has a tricky move. He appears to be
2 turns late for the Lisbon action. Or is he? He can move 1S, then a CF will
teleport him SE--allowing him to catch up to the army, as long as he also uses the road being built now.
The Oporto survivors heal and join for an overwhelming attack at Lisbon.
The good thing about
Joao getting slavery is that he built granaries and
both survived! Yes, I have 2 Terraces with borders popping in only 15 turns.
Washington
Not much to tell. I
pillaged his horse before taking Oporto. See the
extra hammer on the tile at NewYork-N-NE?
He didn't have slavery, so I could just pile up my Q's and attack when ready. No need to worry about threatening him.
NewYork and Chicago fall. I have like 7-8 Q's and lose one per city.
Wash is left alive in a far SW city he recently settled. Fine, I'll ignore it. I'll put him to good use later
DeGaulle
From Chicago it was North to
Paris.
Once again, I let him finish the Horses.
I watch as Paris trys to build a settler while Orleans is doing an archer at 1 hammer/turn

Since I can monitor this, I wait a couple extra turns with my 8 units (a couple of well timed reinforcements) for the worker to also complete the
Cow Pasture. I can work that without knowing AnimalH. I cannot, however, work the horses even tho the pasture remains.
T89:
Paris Captured, now Size 3
1st ring has: cows, horses, farmedFP, Clam, and gold! I need to mine the gold. DG doesn't even have mining.
Meanwhile:
Sule (T79) and
Darius (T84?) got
Writing and OB with me. they have all the gold in the NE. These are both popular alphabet techers in the past for me.
T87: I get
Writing and OB with all
Planning ahead:
With Alpha possibly coming sooner than normal, I need Cuzco to pop borders for marble. I try to work in a
Terrace among the needed Q's primarily for the culture. I've decided to chop another pre-math
60h and whip it too. Normally there'd be no point whipping until the granary is have full (is that a

Hot Tip? everyone knows that.)
Everyone else in the SW is trying to get a nicely timed
Terrace using chop and/or whip.
War Plans
Allow DG to pasture Pig and take DG's last city. I have to because in 15 turns it will pop borders now that it is the capital. Otherwise, I'd probably leave it with him and worker farm him. I have major cashflow problems, so Washington will probably get this city for a while.
Another reason I need that city is because of the ~100 capture
Same with
Berlin. I'll have to do that city, but keep it for myself.
then it's off to
Willy...or his direction anyway. I planned well to have the roads for the army, but like I said earlier, I didn't get the roads in time for OB/trade route income
Speaking of money. I'm losing -50 gpt

! and I only have enough for 2 turns.
That's a problem since I have about 17 turns to go on Math--if I could stay at 100% (which is not going to happen)
I only got about
200 or so failgold from
StoneHenge when Roos built it early
T84.
Hot Tip:
cut IND Roosevelt...and while you're at it,
add some more like DeGaulle and Peter. The other AI can be hard to manage when I'm DoWing Fred 3 times and Joao twice. That's why I kept the Washington war going--so there'd only be 1 DoW there. Fortunately, no one else is annoyed yet. I was able to OB them.
Keeping them Cautious means they might trade gems, fur, silver, or Ivory, etc.
Research
I'd have to call
Fishing a required tech. It's needed as much as Mining or wheel. Especially with no cottages, so I did that before pottery. So getting that in a Hut makes the game a 'keeper'.
I got to Writing (87) 7 turns faster than I did in my Score game (but that was on Huge with higher tech costs)
I was not able to maintain 100% research on the way to Writing.
Math is going to be a struggle. With Henge gone, the only way to make money this early in the game is
Quechua whip/chop overflow. I'll revisit that strategy next turnset.
G.General born. Probably a super-medic. Another advantage of Quechua. They start with Combat I. So you can make a 2-movement medic with the extra promo.
Hot Tip: Just like before, when I sent Q's ahead to harass Wash and DG, now is the time to explore thru Just and Willy and de-fog all of the AI. You can spot possible late targets, and allow viewing of the city production (looking for wonder builders). One Q can completely deny horse/metal if he gets there in time. It's too late for most, but worth a shot. Don't forget to defog a complete coastal trade route path.
Mansa 
did
pottery, Writing, masonry, and now sailing. He's going to be a threat for the GreatLighthouse.
