The main drawback of Alternate Reality Gaming, compared to other genres, is that it lacks reusability; typically it cannot be played freely by anyone, anytime, anywhere. However, with the help of modern technology, especially in the mobile devices section, this can be overcome, at least to a certain extent. Therefore, we propose a conceptual framework built upon these challenges raised by other ARGs, a framework meant for game designers and developers that wish to create reusable ARGs, to add reusability to their own ARGs or even turn their digital games into a mixed experience. We designed it by reviewing relevant literature of past ARGs that had a reusable or a digital component, from which we have drawn conclusions and mixed them with our own ideas. Then we tested it iteratively by developing two prototypes and evaluating them through user feedback.
