Anybody interested in an SRD for Mini Six? Since Mini Six is under the Open Game License, I have created one for it, Minimal OpenD6 (https://github.com/tkurtbond/Minimal-OpenD6). (It does not include the Product Identity portions, of course.)
If you just want to read the rules I still think the original Mini Six: Bare Bones Edition (https://www.drivethrurpg.com/product/144558/Mini-Six-Bare-Bones-Edition) is a great document, packing so much into a dense but readable layout, so download it for free or get a print copy. However, if you want a custom version of the rules, whether you are producing a completely new game or just want a version of the rules with all your house rules incorporated, this should be a great starting point.
Why start with Minimal OpenD6 instead of of OpenD6? Because you want to start with a minimal core and add things gradually, rather than starting with a very large document and cutting out everything you don't want! (Different approaches work better for different folks.)
Minimal OpenD6 provides reStructuredText (https://docutils.sourceforge.io/rst.html) source for the document, as well as simple PDF, HTML, EPUB, Microsoft Word.docx, OpenOffice/LibreOffice .odt, and Markdown output. Conversions to other formats are possible using pandoc (https://pandoc.org/) or other means.
If you just want the output files without any of the stuff used to build them, look at the releases (https://github.com/tkurtbond/Minimal-OpenD6/releases) page in the repository for a zip file.
Thanks! Checking it out now.
