This difference in approach is actually visible from differences in map geography. To examine a small sample, here are the overworld maps in Baldur’s Gate, Morrowind, Oblivion, Fallout and Fallout 2. By contrast, here are overworld maps from Dragon Warrior 3, Lunar, Lunar 2, Phantasy Star 4, Final Fantasy 4 (B), Final Fantasy 6 and Final Fantasy 9. The mountains in the Fallout games are passable; the mountains in the Elder Scrolls games are sometimes passable; mountains in the others are not. Compare the frequency with which one encounters impassable mountain ranges or oceans among the wRPGs versus the jRPGs. Notice anything?
