Let’s pretend Interactive Fiction is Software. And you are an author. How would you describe your user community?
Or perhaps IF is the next evolution of Literature. And you are an author. Who then are your readership?
This topic sprang from another which discusses potential future enabling technologies for Interactive Fiction.
In support of that, here is a place to describe the potential future Audiences of Interactive Fiction.
The potential audience for IF is anyone with a computer who buys/downloads (depending on price point) software with interactive narrative of any description. Getting it down to an actionable size of audience means a lot of decisions about the IF (probably enough to have a playable demo already in existence and play-tested with some potential audiences) have to already by known. Marketing never wants to wait that long.
This is why I don’t like this sort of marketing question - it’s nowhere near as helpful as the people who ask it think it is, even if one is considering IF with a specified narrative and gameplay mechanic.
