What is Yags?
Yags is Another Game System, one that is meant to be free, generic and modular. There are a number of different articles which describe the different aspects of rules.
Articles are mostly independent, though all rely on the core rules given here which detail how to define a character's skills and abilities, and how to perform task resolution.
Combat, character generation, magic and other topics are described elsewhere.
Yags is meant for table top, pen and paper, role-playing. Though a computer game based on these rules is in development, it is not a computer game itself. These rules do not explain what a table top RPG is, or how to play one - it is assumed that you already know all this, and are simply interested in how Yags differs from other game systems.
All these rules are available for download from the Glendale website. http://www.glendale.org.uk/yags/ .
