never mind your right, I bet I was comparing your files though a loaded game.

This is it.

I have no plans for any other variants, but all I am saying is, this is essentially no different to having two items per city, other than it can be any two items, disregarding what the building shows.

So whilst this may show 60 demand for x y and z, that's essentially 20 of each or 60 of one.
The other mods may show 20 for each.

Yes, lower numbers of goods = less profitable lines, but that's why you grow the cities, to increase demand and its easier to grow from lower demand numbers than higher.

The population modifier percentage, is essentially the percentage of goods you are supplying versus the demand, so its easier to supply 10 out of 10 items and get 100% population modifier than it is 100/100 items to get 100% population modifier, of course, as the city expands, demand will increase and the modifier will lower again until you fulfil the new demand.

No, I wanted one where as I supply more products the city grows faster. With the one you linked each building only accepts one item, so the total quantity of any item demanded is very very low, so low that a supply route wouldn't be profitable.

In the end what I want is a economy model where a, for example, commercial building will accept all three types, all at the same quantity. So I can initially supply food, which boosts growth, then supply tools, which further boosts growth, and finally goods which boosts growth farther. That way the total demand of those goods goes up as the city grows, which makes the lines ever more profitable.

Is this possible?

This mod shares demands so you can supply one city with a single item to satisfy building growth, since it uses X OR y OR z.

I would think this would work better, since it uses x AND y AND z:

I'm glad you made this available, I want to supply all goods to all cities and do so with the maximum city growth. I assume that if you fully supply commercial with, say, food AND goods that you get both at 100% and that will drive more city growth?
