Already been mentioned a few times, but just want to add my voice to it as well.
I think it really needs an overhaul when it comes to the relational, political and diplomatic aspect. Some way that make your characters actions impact the world and people around you. Stuff like the Fight Together Relationship mod is great. It’s so simple, but ofc other lords would respect you more if you fight with them.
I guess Taleworlds has a lot on their plates though, so hopefully the game will get more depth down the line ?
