Georg wrote a pretty interesting article about the development and background of the Burn The Boards project for Madewithunity: http://madewith.unity.com/stories/burn-boards-making-unpleasant-reality-immersive-gaming-experience-1.
I was involved in the creation of the project and was part of the design team for it. The problems of electronic waste and the associated health risks of workers are a topic that interest me greatly. If you want some insight into how that serious game was made check out the article.
