Albeit a little outdated, and hard to read in places, this still can be used by prospective GMs who want to play out the Possibility Wars from the beginning, with rumors and plot hooks abound. Summarized in the Infiniverse Guides, this is a rare opportunity to revisit RPG history in the making as being the first game to have players decide the outcome of published material - a modern day reality with the Pathfinder Society modules. Back in the snail-mail days, however mailing in the responses was a milestone in creativity. Well worth it for the material it provides, and a solid historical perspective on one of WEG's finest.
