The Planarch Codex is one of the most elegant designs I have seen. It embraces the rich character of the old Planescape and the implications of such a society. It embraces the freebooter; the freelance "troubleshooter" who would be desperate enough to wander across the planes. It explores culture and ethnicity in a thoughtful yet gamable fashion. It's a massive wealth of rich seeds and inspirations to make your games all that much more awesome. It's also free, which is another fantastic point in it's favour. I look forward to the next Planarch Codex.
