Made this work with FlavourMod 2.7.0.
Oh and multiple Terrain Yield Changes for each civs are possible now too. I'm sure you'll find some use for this too.

Great! And you are right, I like to increase ties between civ and it's default enviroment type
So, impatiently waiting for the release. And folks, be patient

I will release just after including Jean's code.
You have no idea how glad I am to hear you're releasing it tomorrow.
Not sure if you mean me or Jean, but anyway,
When i try to install this mod- says cant find mod/fall from heaven 2
then gives me choice to abort or continue
Propably Civ4 is not installed in the default directory. If the installer prompts you for the civ4 installation path, you should modify it accordingly.
Of course, it is assumed that you already have FFH2 installed. If not, install FFH2 first.
First, you need to have Civ IV properly installed - both FfH and Orbis read from the registry to install in the right place. So it does not need the default path (mine is at F:/Civilization IV), just any valid path at all.
Then install FfH2.
Does FfH install properly and work?
If so, patch it to Y and then install Orbis.

What you propose is very complicated code-wise and certainly well beyond my abilities.
Also, it is not really a solution to the thing we discussed. The problem is, how to add an ability to move some excess food from one city to the one that needs it, not global food trade. Well, it would be nice to be able to import food from another civ's city for gold. Certainly something that is all around us... But I want total amount of food in the world to be constant, not something that you can easily adjust using slider. Want more food, build more farms, you know.
Currently, I think Tarqueline's idea is the best one. I am sligthly worried about the amount of buildings that would have to be added (two per every

traded - i.e. two (+ and -) per 1

trade, two per 2

etc. and we certainly do not want to limit it to just one food trade...). Plus there needs to be a way to remove them... And still have the same total number of + and -
