I'd personally really enjoy getting along with the far harbor trappers as a fellow cannibal. The bethesda launcher won't even install for me, so I'm excited to learn some of the things still in the game files. Edit: As to the original question, if I recall correctly, the whole infamy/reputation system required faction lists and disposition levels. I wouldn't be surprised if those, too, were left over in the game, but on the same note wouldn't be surprised if various npcs were attached to factions they had no business with. Bringing back the faction/infamy system is probably something I look forward to second only to stealth kills being made possible.
