Flying/Swimming
Another thing I've not seen anybody talk about, the actual possibility of proper flying mounts (not Ahriman). Along with swimming, this bothers me. Understandably corners have been cut in level design for areas we weren't supposed to see - for example there is just empty space behind rock faces. Another issue making this difficult is the removal of "seamless" areas - such as flying from area to area.
Boat making was mentioned by Tanaka (screenshot). Not sure how this would work or what would be the point as we can't control them, they would need to design an ocean to allow for sailing between cities.
Mountain/river (etc.) chocobos would be cool and could provide access to otherwise unaccessible places, they would be rare and need to be bred like in FFVII.
Now all this leads to my main idea, AIRSHIPS!
- Players would see your LS airship in the sky, much like the garlean airships flying about in v1.0
- The inside of the airship would be instanced for LS members.
- Could be piloted by one person from a birds eye view.
- Would be more expensive than housing and very rare.
