Incremental buying

Gee, that type of explicit response made mine look quite wordy.

The city will mark it as a taken commodity until it's delivered to complete a wonder.

OK, I'm with you for all the rest of the above post. However, on many, many occasions, I wind up without any commodities to build in key trading cities, despite having delivered all caravans/freights previously built.

I find that delivering freights to the city without commodities can sometimes free up new commodities to build. And sometimes it seems that if new advances are discovered, or the city grows, new commodities to build are generated. For example, uranium only seems to show up after NF is discovered.

Do any of you smart guys (meant without irony ) know any definitive ways to free up build commodities? Or when and how it happens naturally?

[rah]

If they're delivered to build wonders instead of trade, they should free up.

For what changes, I've seen it change when another player gets trade, or when I or another player gets banking, economics. Not all cities change.

I had one the other night in an MP game, where the caravan was one square away from the city and it was demanded, I hit the wrong button and continued moving it. But since I had 2/3 left i moved it back out of the city and when i went to deliver it back, IT WAS NO LONGER DEMANDED. ????????????? Now we don't allow tech trading so no one could have gotten a changing tech in the time it took me to move the caravan.
SO even just answering the delivery question can effect demands. (this seems to happen more in fringe cities than core cities)
Yes I too will sometimes deliver non-demanded commodities hoping to shuffle the deck.

These are some examples on why it has never been fully understood. The basic concepts are known, but the exceptions are many.

That makes sense.

Trade... Banking... Economics... those are all on the same tech path, correct? I need to look at my tech tree (I can't unfold it at work, people would talk) but perhaps if there is a relationship between certain techs and changing of supplied commodities, it could influence research paths? If your trade city (or OCC city) is capable of 500g caravans but can't build any, it would make sense to divert the tech path... in order to get subsequent techs faster. I think.

These are some examples on why it has never been fully understood. The basic concepts are known, but the exceptions are many.

I haven't finished my hut tests... so don't look at me

One thing that I did notice, is that I have seen changes in my outer cities, when my Captial didn't. So some of these may not be approriate for OCC.

You guys are too smart!
I try to put my friend Niccolò at work finding the answer for himself and you give him the answer.
Luckily the answer is so complicated that Messer Niccolò will probably be compelled to open his lab nevertheless
(BTW I think that Xin Yu has an almost complete theory about 'refreshing' demand, but he is very busy with his civ manager at the moment ...)

[rah]

Yeah, Xin is good, but there always seems to be an exception to the rule.

To clarify, the cost of rush buying a row of shields is not a constant 2.5g/shield, that is just an approximate cost - figure a bit less for the first row, 25g for each successive row, usually up to 50 shields for a camel.

IIRC (and I probably get one or two wrong...), the
Cost per number of shields remaining:
10 - 25g
9 - 22g
8 - 19g
7 - 16g
6 - 13g
5 - 11g
4 - 8g
3 - 6g
2 - 4g
1 - 2g

In other words cost of the 1st, 2nd, 3rd etc. shield are
2 2 2 2 3 2 3 3 3 3
So I like to buy 1-4 shields, then 6, then 5, then 7...

sorry, bad hit

Thank you for the link, SlowThinker.
It is real fun to reread it now and notice that supposedly good players had really strange ideas about rushbuilding, and that was 18 months ago
