An iconic RPG setting, with a really authoritative and detailed write up of the history of the genre. Beautifully laid out too, in full color, to emulate it's source material. It's not a complete game, however, as you will need to Basic Hero rules (130 pages!) at least to play. The rules themselves scale very well in the supers genre (better than most other 'generic rules'), but are pretty arcane in their implementation of three-letter acronyms and the like.
