Dangers and Dweomers is my personal spin on Dungeons & Dragons. A complete, cheap, OGL game.
As much as possible I streamlined the S&W system, filling what I found as gaps with material from the BFRPG and the Srd. As always my ideal model is the D&D Rules Cyclopedia.
The latest revision, the version I play with when I get to, is “The Blue Book” currently available on DTRPG.
