In recent years the emergence of multiple game platforms (e.g., mobile, specialized consoles, PC) along with the rising interest in game creation by users with limited technical background calls for the development of high level authoring environments that base the creation process on abstract game models and automate their implementation. This paper describes our research towards the creation of such a development and execution environment that incorporates a graphical authoring environment based on an abstract model of common action RPG games along with a 3-D rendering client that automatically translates the resulting game into an OpenGL ES implementation.
