Not really sure your map is proving your point
@Ixal. You realize that's a pretty small area right? If your argument is that most people stay within a hundred klicks of wherever they were born, and that's your idea of major travel, well, sure, okay. Because, just to put it perspective, your map there? That's about the distance from Waterdeep to Baldur's Gate.
But, hey, I still don't know why you folks are arguing with me. The first line from the video said EXACTLY what I'm saying. The overwhelming majority of people barely traveled. Heck, as you say, the trip to Mecca is a once in a lifetime thing.
That would, of course, be the point. FR/D&D shouldn't look like it does. But, hey, it was good enough for Tolkien, so, we just gloss over anything even remotely resembling logical world building. We'll make any excuses, ignore anything we need to, just so we can have our Ren Faire settings.
