Α Focused Authoring System (FAS) is a digital game template that contains both digital and textual files and its main feature is that it can be authorised by others. It is a useful tool that allows users other than the designer to develop and create their own game. Four FASs have been developed in the GAMMA project, two for each authoring tool MaLT2 and ChoiCo. The FASs are used in the development of the GAMMA games.
