It's 1st edition Pendragon. Even if you don't want to play a game about Aurthurian romance this edition of Pendragon is the ur text for genre emulation based roleplaying, and it still does an amazing job.
I really like the concepts introduced to me through the book. It is a different way to roleplay then I am use to and has opened me up to new ideas. However I doubt I will be able to convince my current group to play with this module. I will probably incorporate some of the ideas from here into my group's current campaign.
