That’s going to be interesting to watch…
Lessee… Empress Lisabetta has vanished, and the Throne is vacant.
The Liberty pact, banning slavery and trade with slaving nations: has it worked out?
Why is my nation getting over-run with barbarians while there is being heavily defended by Imperial armies? (Applies to almost everyone, I think
)
Generally, the subjects that everyone will have an opinion on are:
- Where the armies should go next
- What the Senate should be spending money on (Economy, Religeon, defensive military, offensive military, diplomacy with immediate vs distant nations)
- The barbarian tribes on our borders
- Eternals.
(Pretty much the whole spectrum of real-world political issues, although rebellions and breakaway regions are at a low… currently)
Opinions will vary from “I know nothing about this” through to “Well if you ask me, I reckon we really ought to…” through to “If we do not do X within 6 months the Empire is doomed!”
As to how peoples opinions line up or disagree, well, I’m afraid that really is something for the field. It’s a good hook into the role-playing, asking opinions on world events. And will likely get you into several IC arguments 
The League… well… Sarvos was sacked by the Grendel not long enough ago, and while a deal has been struck with them, it’s not a good one. Holberg (province) is hosting a large tribe of orcs with a slave complex who ran from the Druj, is it worth it?
