FYI, those wishing to get a preview of the game can download
a free PDF of the PDQ# core rules from Chad's AtomicSockMonkey website.
The rules look comprehensive enough to be used on their own to develop your own games (they're basically an expanded version of the existing PDQ core rules), though there is some swashbuckling-specific content. On the other hand, it's hard to think of an RPG setting that couldn't be improved with the addition of a bit of swashbuckling...
