Description

NPCs in games are props. They have scripted lines, fixed routines, and no memory of you. You can save a village, come back a year later, and the blacksmith still greets you like a stranger. The world doesn't move— it waits. No matter how many hours you play, the characters around you are hollow: they don't grow, they don't grieve, and they don't remember.
