The gameplay loop when there's ongoing wars is solid, Its fun to participate in big battles and sieges (even though siege towers/pathing still are broken AF) and economy wise you are able to sustain your parties/garrisons by winning battles etc.
However, the gameplay loop when there is no ongoing wars is really tedious and also makes party/garrison managment frustrating because you are no longer able to sustain a steady income, which means disbanding tier 5+ troops that you spend a long time training. In terms of gamplay, while some quests can be fun but they also quickly get repetitive. Same can be said for tournaments, while fun once in a while they are practially constantly held and also quickly get repetitive.
Because the game is early access I thought it would be fitting to come with some suggestions that might allviate the tediousness of peacetime gameplay in Bannerlord.
The recent addition of rebellions is a great feature that could be used make peacetime gameplay more interesting. It would be great if rebellions werent just tied to wether or not a city was recently captured but to relationsship between lords and their monach. This would mean that unsatisfied lords might rebel during peace time (maybe even form a coalition with other unsatisfied lords) which could introduce the choice for the player to join and fight for either the kingdom or rebels.
Another thing I thought could be interesting was a more meaningful feif interactions during peacetime were you have to make decisions for your fief and people sorta like this mod(

Another possibility off the top of my head, could be an addtion of companion quest/activities during peacetime. Hideout raids with some meaningful backstory (sorta like when you free your brother).
In any case I think peacetime gameplay is pretty lackluster atm and definitely could use some love before release. Feel free to add any suggestions you might have.
