i remember something about being able to build airships in your basement once housing comes around... There must be more to this as there needs to be a reason to build airships and i don't think we are talking about making massive airships. Smaller Personal ones for free roam, or structured flights

I think it would be cool of there was an "Air" zone above the world where airships can travel around, possibly to new continents once the world is expanded, all the while being able to see the terrain below you. put a Sky city up there as well and some airship PVP. If we can build our own airships and equip them as we see fit I could see that being great PvP content.
