Let's use this thread to discuss how airships could be implemented and what features we'd like to see.
Tech:
What kind of tech would the airships use? I could see 3 different levels of tech.
Balloons:
The most basic of ships. They use balloons filled with...some lighter-than-air gas. This designed is shared with the Ixali balloons (don't wanna spoil anything to those who haven't done the Ixal quests.
Because of their low tech, these airships could be the cheapest or the earliest available ships to us. I haven't seen this design with weapons, but given the open deck design and the vulnerable balloon, I'd think these ships are ill designed for combat. Think of these ships as the smallest house.
Propeller:
These ships are slightly more advanced than their balloon cousins. They sport propellers for lift and armor too! Decks are covered in armor, making them good candidates for Airship-airship PVP/PvE. Faster than the baloons, yet more expensive as well.
Compare these to the medium houses.
Cerulean Power:
This design has the best weapons/armor. They are also the largest and fastest ship. The most advanced airship available. Built using stolen plans from Garlean shipwrights (Thanks Cid).
Acquisition, uses, and crews:
How do we get an airship? Is it like buying a deed then actually crafting the ship using DoH? Or will it be as simple as buying the entire ship pre-made? Yoshi already said there would be locations that are only accessible by airship. Would that mean they will actually be acquirable by most of the population unlike housing?
There may be special sky battlefields that pit our ships against Garlean ships. There could also be PvP Game modes as well. Each ship would need abilities that would be fitting for combat (like "use cannon" "Use missile" "Evasive maneuver" I dunno.)
The balloon airships are crewable by a single person, a pilot. Would the more tech-y ships require bigger crews? How would/should that work? Would it be like a full-party enters the party leader's ship as his/her crew? Each person takes a different system like 1 person is a pilot, one person is the navigator (Highlights enemies), and the rest of the people work on weapons?
If this works out, the last thing to add is the Sky Fortress!
It could work as a flying FC HQ with a huge hangar for the members' Airships. Sky Fortress PVP ooooo.
All aboard the hype train! CHOO-CHOOOO!
