[T]he main thing that’s hard to do in IF is build a story where there’s a lot of internal character development as opposed to external action. There are some ways to approach it, but they’re all challenging, and there aren’t very many examples of IF where people have done it successfully before. Whereas if you’re writing a book, you can just sit down and write some lines of internal monologue for your protagonist, and it’s not inherently different from writing a fight scene or dialogue or anything else. —Emily Short, interviewed by Bill Loguidice —Interactive Fiction and Feelies: An Interview with Emily Short  (Armchair Arcade)
