Having just played FFX again for the first time in a while, I'd like to add something to my previous statement. Selecting locations from a list isn't such a bad idea. I always use the Ragnarok's auto-pilot in FFVIII, and using the list is not dissimilar. An ideal design, in my view, would be to have a world map to explore on foot/by air, and have locations previously visited on a list for easy access. I think it should show the airship travelling across the world map, and not simply acting as a hub for Traveller Sphere teleportation.
