What this means for your play
Choices with practical meaning.
A settlement is not a paragraph that changes whenever you ask another question. Its people, services, resources and history are recorded by the game. The next decision starts from what actually exists.
Make plans against a real world
If a settlement has one suitable specialist, you have one possible local provider, not an unlimited pool of experts. If a component is elsewhere, reaching it becomes a real task. Supply, services and location give your choices practical meaning.
Keep the history you created
Owned items stay owned, consumed materials stay consumed and an unresolved fact stays unresolved. The world can remember an NPC, a changed relationship or an earlier shortage long after the conversation moves on. Continuity comes from recorded state, not the narrator guessing what happened.
