There are 3 human npc types in Starfield, the Mobs, the Radiants, and the Uniques.
-The Mobs are what you actively see roaming about the major cities, they're meant to give those cities some life and have a purposeful low quality design to prevent putting too much stress on the engine
-The Radiants are npcs who are usually randomly generated for things like populating small settlements, being guards, crew, or enemies, and being radiant quest givers or targets. Their design has more effort put into them
-The Uniques are npcs that are designed to actually stand out from the above, they're usually tied to various major and side quests and some can be crew and companions
