Simple Technical Explanation
The eLearning Reusable Games is a subscription service that helps designers and developers or anyone who develops eLearning courses add visually appealing and highly engaging interactive games and exercises. The subscription service consists of three parts: (a) the proprietary Flash engine and the XML files which control all of the assets and interactions; (b) the assets, namely, image, audio, text, avatar, video, etc, which are independent of the Flash engine; and (c) the Web-based Reusable Generator which allow designers and developers to select, edit, download and archive their own versions of the Reusables.

It only takes three steps to produce a Reusable: (1) Set-Up, (2) Create Content, (3) and Publish.
