Sword of Air is a combination big-adventure and mini-campaign from Bill Webb's campaign that he started back in the 1970s (and still runs). So this is going to be vintage old-school stuff, especially if you're getting the Swords & Wizardry version.
I'll probably write more about this soon. Kickstarter took us by surprise with a fast approval of the project, so I'm a bit slow.
