2. Add ability to convince neutral people (like Lone Wanderers, Travelers, Fishermen, Hunters, Farmers, Salvages, Trappers maybe even some of patrols like Junktown Scouts etc.) to join your party and follow you (e.g. you make friends and roam together), again can be based on speech and HP difference between you and potential follower (the more difference the more speech required to convince. Another idea is that you can try to convince ONLY the people who is traveling alone (e.g. can be even an encounter with single raider).
