Starting this idea pool bright and early. This pool will be for coming up with ideas for questlines concerning the other factions that aren't Raiders. Minutemen My Massive quest idea that's too big for one post. Brotherhood Gain "Vassals" through Teagan? Diplomacy for gaining control of other settlements. Instead of recruiting through your normal methods, you'd have to build a plot to recruit settlers in "vassal" settlements. You'd also pay caps for recruiting drives. Drugs wouldn't be an option. (The Brotherhood has high standards) Railroad To be honest, I'm just including this for the sake of completeness, since the very idea of the Railroad owning settlements is all sorts of silly. Institute Allow for both radier-ish playthrough style and diplomatic, where you can either outright enslave the wasteland or have a more minutemen-style approach. Outposts would consist enitrely of synths of course. Perhaps some plot (Industrial 3x3) to build them? Mechanist (yes, I'm including this as a faction) You'd start the mechanist questline through a comic book. First quest would be to build a second in command. Recruiting would involve you building robots with the workbench, or using industrial city. I know Industrial City includes these, but some plots to build robots would definately be required. Maybe a 3x3 plot where you put robots parts into a container and it continually builds more robots with said parts? Or you build a robot once, save it, and it builds that robot over and over? Enclave (Would most certainly require an external mod for it) PS: I think you guys misunderstood. I'm trying to come up with faction questline ideas, not ideas for factions in which to give questlines.
