Today I've got a little Swords & Wizardry White Box treat in the form of a 1-page "referee screen." It's got pretty much all the tables you'd need to quickly reference during a game--except I could not fit the spell lists on the single-page format and keep the font a reasonable, no-microscope-required size. :-)
You can get the PDF right here.
Also ... I've finally got Hogtown Games (my vanity RPG publishing imprint) supplements I'm ready to announce...
The first freebie PDF-only adventure, Golden Eye of the Kobold King, will be released in late May. This will be about 32 pages, digest/booklet format, appropriate for 1st or 2nd level characters, and usable with any old-school rules set (has Swords & Wizardry stats). This one will be artless.
The second module, The Purple Mushroom Inn, will be released in late August. This will be at least 32 pages, digest/booklet format, print-on-demand and PDF, appropriate for 2nd or 3rd level characters, and usable with any old-school rules set (has Swords & Wizardry stats). This one will feature art by Del Teigeler, Stefan Poag, Brian "Glad" Thomas, and Fred Dailey. Pricing TBD on this one, but it certainly won't be an arm and a leg. :-)
Until later, cheers!
