I am working on “Ultraviolet World,” a hack of Jesse Strandberg’s “Homebrew World” for use in The Ultraviolet Grasslands.
So far, I’m hewing pretty close to Homebrew World, although I am adding back in a few things from vanilla Dungeon World, such as weapon tags and a slightly less-abstract money and treasure system. I am also pulling in a bunch of mechanics from UVG, including a good chunk of the caravan travel system and the buying/selling trade goods system.
I’ve converted all of the playbooks except the Paladin and Weilder (which don’t really fit the setting) and the Druid (needs more customization for the setting). At the request of my players, I made conversions of The Earthling playbook from Adventures on Dungeon Planet and The Con Artist (from a collection of thief character playbooks from an author whose name escapes me at the moment.)
I’ve also written my own version of the HBW Basic and Optional Moves. Most are identical, but I had to tweak a bunch due to the UVG’s overland travel time-scale of one week. The other challenge is getting the right level of abstraction for equipment. Both HBW and UVG do so in very differnt ways, and I’m not sure if I’ve quite squared that circle.
I am in the process of making a new blog where I can post this stuff, and I’ll put up a link when it’s ready for others to see.
