So....limited teleportation with a high cost could work. However a menu system where you just select where you want to be seems pointless. What is the point of all the cities if the only thing you are doing is zipping between them to meet up for some social encounter? Getting to a cave should be just as much an adventure as getting to the bottom of the cave. So lets make the overworld map better and more immersive, because if all we get is travel on it why bother? This is why it is shocking to me that they will go live without having overworld roaving encounters in. That's at least something to make the map interesting....at the moment it is a static map.
