Due to The Law of Conservation of Detail, towns and cities in RPGs rarely have an observable population measuring more than a single digit (or, at most, the 'teens); this is far smaller than any realistic level of basic economic sustainability. Some games Hand Wave this by implying the town is much larger via expansive background images; our heroes, for whatever reason, are only visiting a small portion of it. Modern games tend to slightly avert this by adding numbers of non-interactable pedestrians into city scenes, giving the illusion of a larger populace.
