I bought Powers & Perils when it first came out. While I was never able to complete building a character, I did have fun reading the rules and the setting details. It was oddly fascinating. So complicated. Every so often, I circle back to look at it again, usually starting at the Powers & Perils website.
What I noticed this time is that a second edition is available on the rules page, which includes both a PDF of the complete rules and a PDF of the Perilous Lands setting information.
The rules are extensively hyperlinked, both in the table of contents and in cross-references, which should make using such a complicated system easier.
Right now I can't imaging finding a group that would be interested in playing Powers & Perils, but there is always a lingering impulse to do something with it.
