People and Sandbox Play
NPCs are not quest dispensers. Each person has needs, skills, loyalties, fears, and a memory of what you did. Ask what an NPC wants before asking what information they provide.
Recruitment
Meeting someone does not make them a follower. A person may need shelter, food, medicine, protection, revenge, or proof that your plans are not foolish. Recruitment is a relationship process: learn what they need, offer a credible exchange, share risk, and accept that they may refuse.
A recruited NPC remains a person with choices. They can leave, demand a change, form a bond with another resident, or challenge your leadership. Their skills help the settlement, but their needs and loyalties create new responsibilities. A larger population is not automatically safer.
Relationships
Relationship scores range from -100 to 100. The number is a guide, not a mind-control meter. A positive score means someone is more likely to give you a chance; a negative score means they expect harm, betrayal, or incompetence. Change the score when you make a meaningful promise, keep or break it, share risk, withhold essentials, or choose one person's safety over another's.
Trust and loyalty are different. Someone may trust you to repair a pump but remain loyal to a rival faction. Someone may stay loyal to the settlement while believing its founder is wrong. Use relationship notes to preserve the specific reason behind the number.
Factions
Factions pursue goals with the resources they have. Their disposition is not permanent. A friendly group can become hostile after a broken agreement; a hostile group can become a trading partner after a shared disaster. Track influence, resources, and headquarters so the world can move even when you are elsewhere.
No correct route
The sandbox has pressures, not a required solution. You may build one stronghold, maintain several linked shelters, join another community, or decide survival here is not worth the cost. Let consequences follow the choice. Do not punish players for declining a hook; let the unchosen opportunity change, expire, or become someone else's advantage.
