A wise man once said:
So it seemed strange that both Seraiel and WT were both improving the copper before pigs and/or corn. Did it have something to do with the timing of the granary or getting it to a 1-pop whip ASAP?
The now improved, and even better, "wise man" now tells:
1

= 1

without a Granary
(Riverside) Grassland Copper (6 yields (+1

) > dry Corn (5 yields)
With a Granary however, 1

gets doubled to 2

so then:
Dry Corn (10 yields) > Riverside Grassland Copper (6 yields) .

Regarding AI beating us to Oracle, I don't see that yet. We're playing on Immortal, AI afaik
always builds a Settler with 100% priority choosing the next build while being at 1 city. (I think I recall that info from
Tachywaxon , but we could check in Worldbuilder just to be completely sure) .
Oracle costing 150

on normal though, changes things for me. 150

is a Settler, then Oracle is still better, but only if gotten, which as said, we can check via Worldbuilder-testruns.
150

imho don't justify a city that has no

, because then it's 300

wasted, because cities without

just don't help at all, and early game, production is very critical. 150

for Oracle are ok, they're better than 75

+ 150

for Marble-Oracle + a wasted Settler.
Regarding warring however, I think 30 cities at 1 AD are not possible on normal speed.
I achieved 11 cities in my 8xx AD Domination game, that's holding a #1 for non-Incan games on Standard / normal. The scaling is simply completely different, maybe 15 cities are possible, 20 I already find unbelievable even with having bonuses.
Just recall the last SGOTM, best teams had 12-15 cities at 1 AD. 30 is possible on Marathon with an ok -> good UU, but normal follows other rules.
Regarding Democracy beeline: I'm very sure, that the speed of Conquest is the greatest factor, and we definately should commit to 1 early unit. I'm leaning more and more away from Horse-Archers though and towards Elepult, because teams in last SGOTM showed, that any form of Catapult war can actually work on the same level as an incredible well executed HA-rush, that's correct, isn't it? TSR and Ducks went for Catapult wars, only we at Kakumeika committed to Horse Archers, and we sometimes weren't sure if we'd be successful at all, so it was incredibly close sometimes.

Out for now.
