Most of the introductory adventures written to ease new players into Dungeons & Dragons over the years have been pretty rough. They're often just dungeon crawls, which might teach you the rules for combat and disarming traps, but don't bother demonstrating what's actually exciting about roleplaying games. Which is the roleplaying. Even when beginner modules leave the dungeon, they tend to dump a lot of work in a young Dungeon Master's lap.
Take Keep on the Borderlands. This introductory module from 1979 gave players a home base in the Keep of the title, full of NPCs they might want to befriend and do business with, and not one of them had a name. They were just job titles like "the provisioner" and "the castellan", with a sentence of description if you were lucky. The Village of Hommlet, published the same year, did a slightly better job providing a detailed location full of characters you might want to have a conversation with, though even that spent more time telling you how many gold and silver pieces every villager owned and where they hid them than who they actually were.
