Stewardship+
Adds some new interactions and decisions that make playing a stewardship-focused run a little more fun.
Interactions Added:
Purchase Title (allows purchasing land from people in your realm)
Legitimize Ruler (allows you to remove all claims on a vassal’s land in exchange for something)
Decisions Added:
Centralize Development (Bonus to capital development)
Modernize Infrastructure (building slot and development bonus)
Invest In Vassals (give vassals a development bonus and get an opinion bonus in return)
Mini-mechanic:
Prosperity
the longer you stay at peace, the bigger bonuses to development you get! The bonuses start small after about 5 years of not being at war, and max out after 20 years of not being at war.
