Love the idea. I remember being awestruck playing so many FF games by environments and how realistic everything felt. I look forward to the cities feeling more alive and things like the cable car help do that.

I also think you shouldn't have to wait for an airship. Heck they are expensive as is. I'd rather one is leaving every minute and they made you wait on the flight for 2-4 minutes. With random monsters popping every once in a while or fun little quests on the airship(like a card game or something) helps immersion.
