Parade
This is very close to the militaristic waring world theme. Location can be a problem, an option is outside around the city wall, which happens to be a lot of room in the open scenes as well. The event is like a semi-festival itself, player can be the one host it or attend it. In meaningful way, my thought roughly take from WB feast, like you can meet characters( notables, lords, etc) so lead to relations. And the host get influence ofc.
Councils/Meetings: War Councils, Councils for issues/policies, Big decisions
This is big controversial I guess. Take current on menu UI-only insta things, into actual scenes. Like declare a war you have to be there, this makes big decision/choices become a big thing, a event of itself. It can just be like current army thing, use influence to call, wait for everyone to start, in a scene. Pros and Cons is clearly there.
Throne Room Audience
The owner of a fief host the event, may be vary abit to faction owner. So those with issues( quests), the icons on the map? They come to you instead when you are the owner. In the same way, if player is not noble they shouldn't be able to just walk up and speak to nobles ( trying to use ingame word choice as much as I can). So they can do so in an audience. The meaning of Audience is a calling for the people in need, notables with issue so the nobles can solve it.
Spent some time with your Family/Clan
The current education screens is ok tho imo, it is on part with character creation at least. This is like a small talk, a scene on wall, this sort alike. I take it from the reaction talk by companions already in game, but just you actively chose to do it. This improve your relationship with them. Need a meaningful application for clan relation tho.
Horse Racing, Shooting Range alike Civil Activities
I see this in the same extend like the current arena/tournament, which need a meaningful entry to main map itself however. It can be a big thing to gameplay itself too, because it can essentially separates combat from both Mount,& blade if you know what I mean. The meaning can be like unique horse reward exclusive to horse racing, best/unique Bow reward exclusive to Shooting Range, this format. But also if there can be a more meaningful entry for arena/tournament, then also these activities, into the live world, then the meaning can step up as core gameplay even.
Really want to see how the scenes can work with other parts especially core parts of game too. I feel like this is where M&B unique at. There is also some related problem like a brute loading screen and static scenes( like time only flow in main map) is standing in the way I think.
