So my tabletop RPG group is currently trying "Inverse World." So far, it's been really cool stuff. It's technically a supplement for "Dungeon World," but as "Dungeon World" uses the engine from "Apocalypse World," knowledge of any of the games that use the "Apocalypse World" rules should suffice.
Basically, think "Dungeon World," but steampunk. When the party can include a sky pirate, a mech engineer/pilot, and a guy with wings, you know you have something special.
