How much commerce are your trade routes generating?

[Thalassicus]

I'm looking at adding a trade route income modifier to State Property, and I need info

If you have any saves in the modern era, how much commerce are your biggest cities generating from trade? (The trade routes are displayed on the left of the city screen). I'm considering a -10% to -25% modifier, not sure how strong it should be, and I only have one save available right now.

IIRC, my biggest city right now is generating 11 from each trade route. I'm at 1955.

Dumb question - how do you get foreign trade routes? I seem to only get domestic routes. At one time, my civics were set to Mercantilism, so it was understandable. But after I moved beyond Merc, the same routes would still be there. What's the deal? Thanks.

You need open borders with the other civs.

You also need Astronomy to have trade over Oceans.

Does anyone know exactly what trade route value depends on (besides foreign trade routes giving more)

Distance?
Population/commerce of receiving city?
Population/commerce of giving city?

I'm not sure how much individual trade routes generate, but you could likely test it in the world editor easily enough. I've found now that ideally the way to solve the state property/free market problem would be to have the Corporations tech give +1 trade routes just for the Free Market civic, rather than your empire as a whole. Unfortunately there isn't any way to do this right now with what we have available, so it'll probably have to wait until the more advanced programming tools are released. Anyways, until then I've decided to just go with -1 trade routes under state property instead and it balances out the civics. Thanks to those who PM'd me
