So, idea pitch. For future updates, if you want you could build of the territory control idea by implementing something like games like XXXivilization that effect the NPCs. And you could make it something as simple as making three paths:
- Harmony: you convince the citizens to live along side the monster and demons.
- Dominance: you make the monsters and demons the upper class along side those that show absolute loyalty.
- Corruption: over time your influence has twisted all those within your domain and turned them into the very monsters and demons they hated.
Basically, you switch on certain laws that favor certain paths and which ever path you favor most becomes the result. With each law having an effect on the hatred, loyalty, & corruption of the cities under your control. Unfortunately, I don't know how you'd code this especially since this game doesn't have a rest mechanic. Also, don't know how well that kind of system would gel with RPGM.
