What is Jazz?
Jazz is an attempt to create a roleplaying game system which is both flexible and easy to use. Jazz, like its namesake, is inspired by and incorporates concepts from many sources.
Jazz does assume a basic familiarity with principles of role-playing and the basics of making up a character. I haven't gone into great detail describing what a roleplaying game is, or defining what "Health" is, for example. These sparse spots may be filled in as time goes on, but feel free to use your best judgment if something doesn't make immediate sense to you. Jazz is intended for my personal use, but feedback and suggestions are welcome. If you think a section is unclear, or needs more elaborate explanation, do feel free to drop me an e-mail with your suggestion.
The rules of the game
JazzCore is the base rule set for Jazz. For games set in the "real" world, JazzCore should be sufficient. For more outlandish games, additional rules may be helpful (or you can just wing it).
Genre modules provide genre conventions, typical descriptors, typical flaws, suitable equipment, and other optional rules for using Jazz to play a game in that particular genre. Genre modules are not mutually exclusive. For example, you might want to use JazzApocalypse and JazzSorcery together to run a Thundarr The Barbarian game.
Here are a few genre modules which were once planned for Jazz. None have been written, and none probably ever will be. So it goes.
