Dangers and Dweomers is my personal spin on Dungeons & Dragons.
A complete, free, OGL game.
I took the chance of writing it after Swords & Wizardry made its appareance, as a base I used S&W, the BFRPG by Chris Gonnermann and the d20 SRD.
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.
