Hi,
So first and foremost think the PM should also get a tablet with the same features as the HM one. And think they should get outfits in their closet.
There should also be set shedules for the Government and Royals, so example, garden party, weekly meeting with PM, grand tour, inspection, award ceremony, etc but it should be possible to edit this shedule. But you must have a shedule.
Allow the Government to make laws like in the games His Majesty’s Government and Oath of Office and let their be special emergency scenarios from time to time to solve.
Create the House of Commons (for everyone) and Lords (for those with peerages or royal pass) and allow elections but allow government pass bypass elections.
Allows state opening of Parliament rp
Allow PM and HM pass holders access to medals and peerages for themselves or the abilty to purchase, but really need more perks for HM/PM pass.
Create a garden party set at BP and DS. Add food and drinks to the dinning room table at bp, one with music box.
Give an office to the HM. For meetings with PM etc.
Create a BP events hall. For balls, coronations, press briefings etc.
Allow civs to be press members, like bbc.
Allow government members be foreign ambassadors too.
Let civs be allowed to work as royal household or governmental staff but can be kicked by monarch or pm
