I spent some time this weekend thinking about Interactive Fiction, and how to implement it nearly. One thing that really struck me about IF programming is that where discussions of ordinary languages tend to be littered with code samples like "function double(x) { return x * 2; }" discussions of If tend to have examples like "when you blow the safe, if the guard is in the recording studio he can't hear the explosion; otherwise he shows up and arrests you."

I suspect this comes from most of the influential IF people being storytellers and writers first, and programmers second. It certainly makes for a fun and surreal change from most programming discussion.
