As everyone knows, BRP is the bee's knees of RPG systems. The good news is that there is, or soon will be, a conversion document for 2300AD-to-BRP on the FFE website. In the meantime, have a look at the author pansophy's thread on the BRP Forums (
Link to thread).
(FT: just to clarify for everyone as this is a long standing mistaken impression, links to discussions of interest on other sites is fine, always has been, as long as they don't in themselves violate the TOC here - such as politics, religion, etc., just use some common sense and you'll be fine, review the FAQs and if still in doubt PM a mod)
