Challenges in collaborative game design developing learning environments for creating games

We perform a general analysis of the game design process, the structure of digital games and investigate the requirements for the use of OpenCroquet as a platform for collaborative game design. Based on our experiences of using a Squeak/Tweak programming environment in many game projects and recently for teaching game design we derive properties of a learning environment for teaching game design in an OpenCroquet environment with a special focus on collaboration.
