Michael Wenman has now published his game, The Eighth Sea. Buy it now from Lulu.
I played the final session of this at Gencon Oz and enjoyed it immensely. It felt like he'd made it the Convention Special Edition because of all the props (a whiteboard! a wine bottle! a human skull!). It uses a great system of making failures easier next time, and successes more difficult. All in all, the result is a game with plenty of opportunity for gonzo and large story telling.
Note: skull may or may not have been an actual human. If it was, the human was about the size of a child.
