A successor to the Patrician series?

One of my favourite economy-related games is Patrician IV (with III also having a place in my heart). Despite having some problems, it is absolutely wonderful at making you feel like you're an actual merchant in a real medieval world, which changes dynamically, both with and without your input. The cities actually need, consume and process the resources and goods you and your opponents transport, what you bring into the cities and with what frequency translates to them growing or shrinking organically, and they can even try to address their situation by issuing missions and rudimental economic policies (such as port taxes, taxation on certain goods, issuing embargos). And while you can become the mayor of a town or even the leader of the Hanseatic League, you are never an almighty, abstract being with total control. Other merchants can still build things in "your" city, you need to get reelected periodically or you'll lose some of your privileges, and if you want to build more buildings than possible with the resources city has on its market, you need to either ship them in or wait for your opponents to do that for you.

I have been searching for a game that has such a dynamic, logically functioning and real-seeming gameworld, which you influence not as an omniscient, all-powerful being, but as a person within this world. The Port Royale series seems close, but nothing else I found works. Do you have any ideas? It can be historical, modern or even sci-fi or fantasy.
