There used to be a staple for JRPGs in that, unlike American RPGs, they had world maps. RPGHead are not talking about a map that shows you a world, or simply a point to point map that takes you to places (ala Fable). What they are talking about is a map where you and your party can explore.
These world maps would be littered with towns, caves, cities, and forests; each with their own name and history. Unfortunately, as gaming gets more and more "nextgen" it seems the concept of a world map remains considerably "lastgen".
