Like I said before, I like your approach in general and also this new update is really "dense", maybe too much ? You should try to explain and test every mechanics separately, so you can learn if they are fun or not!
For example I'm not sure if the player can keep track of all circles and relationships in order to manipulate them, I mean I can see some sort of "information overloading " ?
One of my problems with SBTT was the interface and all the stuff happening together. I suggest you to take a look to Europa Universalis IV from Paradox, or Crusader Kings 2, where player Is able to follow a lot of things together because of the real time pause, of course, but also because of the interface.
My suggestion here is to work a lot on the UX and UI, maybe with some prototypes, to find the better way player can interact with such complex world you have in mind!
