Some initial thoughts:
1) Turns are very confusing. 99% of the time I don't know who travels where, maybe show chars' plans to travel or make travelling longer. Tavern POIs? Would be great. Mb slower turns.
2) Maybe adding an outline to selected city?
3) Showing chars' holdings in their lists.
4) Pausing on spacebar.
5) Pausing on events.
6) Is negative population in POI ok?
7) A little bit of tutorial is gravely needed. Like, when you can influence smb, manipulate etc.
These are just basic thoughts. Good concept, I hope you will develop it further.
