At long last, Slumbering Ursine Dunes, an old-school sandbox setting that Chris Kutalik, our creative DM, created as part of his Hill Cantons campaign and turned into a full-fledged adventure module via Kickstarter. It has a distinct Eastern European/Slavic flavor to it, filtered through a sardonic Austin viewpoint that predates hipsters by a generation. And there's a whole lotta stuff in there that we tabletop players never saw during our games. There are some great ideas in this adventure, so check it out.
Also in the package I received, Original Edition Delta: Book of War, from the author of Delta's D&D Blog--it's a medieval/fantasy miniatures wargame rules based directly on old-school D&D. One figure represents 10 men, and combat is resolved by rolling d6s, allowing DMs to fight out those large battles without taking forever. I like the simplicity of this ruleset, and I'm looking forward to trying it out.
