A Class Grammar for General Games

While there exist a variety of game description languages (GDLs) for modeling various classes of games, these are aimed at game playing rather than the more particular needs of game design. This paper describes a new approach to general game modeling that arose from this need. A class grammar is automatically generated from a given library of source code, from the constructors and associated parameters found along its class hierarchy, to give a context-free grammar that provides access to the underlying code while hiding its implementation details
