I did watch it...after I posted that.
But I did watch it all of the way through and I think the post still applies.
It is/will be, certainly, a fascinating and cool reimagining. I personally think you might be overthinking it...and/or focusing a bit much on the actual map/cartography...since, as you say in the video, none of the actual material (cultures, religions, etc...) is changing.
I mean, the map
is important, of course. As you are working toward an actual published product, naturally, the map needs to be "right" since it will be in print and "official" [immutable] -at least for a time. And what, presumably, you've settled on would certainly be something to set it apart...which is always nice/good (when you know it will be compared to other published settings).
You get dissatisfied with the actual shape of the world and look of the map...and change it. It's cool. It was interesting to watch the progression over the years. If turning it on its end makes it much more interesting and fun for you...then great! They are some beautiful maps. Those couple at the end [that I know you couldn't/can't use] where you were sticking region names on worked perfectly.
The different strokes of different folks are also always interesting to me as well. I can't say I, as a world builder, ever really focus that much on the world's actual map. The cultures, nations, religions, interactions thereof, specific locations (a special citadel or temple or dungeon or lair), histories and legends, are infinitely more interesting for me. In fact, I think the general, geographical, SHAPE of my world['s primary continent] has been roughly the same for nigh on 30 years. Places change. People change. Countries or kingdoms or empires, gods, heroes, and villains that interest me come and go. But the coastlines? The mountains? Sure here or there, one map might look a little different than another. Maybe a not so prominent river gets missed or I forget a town in one country that a given group of PCs aren't going to be anywhere near. But whether the nordic/scandanavian/viking analogue tundras are in the north or the east or south? Doesn't really ever cross my mind. The arabian/mesopotamian analogue empire of Thel? Still going to be in a chunk of the huge desert in the center of the continent. That kind of stuff pretty much doesn't change.
Interesting/fun video, as always.
