How can we help people design well-formed and innovative games? The design Patterns of Christopher Alexander is one methodology that has been proposed to assist in the design of well-formed artifacts. However, most work on gamedesign Patterns to date has opted either for “best practice” style Patterns – or for an alternative model of Patterns to support game innovation. This paper describes initial work to develop materials to help developers identify and formulate “best practice” game design Patterns – and to use the resulting Patterns as part of creating innovative games.
