The syntax of Fountain Exponential could have many parsers in many different languages. This one being in C#, would make it possible to include it in game engines that support C#, like Unity, Unreal and Godot.
Alternatively this parser can be the basis of a converter to go from Fountain Exponential to other formats. Once parsed the data structure could be converted to a data format could be incorporated in a game like Comma Separated File (CSV) or RESX XML resource files.
