Socialization.

Yes, of course. FFHtR would need more interaction or even teamwork with NPC. Of course, I should enchant AI for group tactics, but, also, Player should speak, recruit, bribe, blackmail, deceive etc NPC.
So, we need some interaction system for NPC.
I don't want to invent something new, so, all NPC would have eight variables of vice and virtues.
So, seduction of some scum, like thiefs, bandits, maniacs to serve Evil would be relatively easy, and so on.
