You've played every Infocom game imaginable. You know all of the ins and outs of the GUE. You've killed Floyd. Twice. Now what?
Write your own interactive fiction game, that's what. Whether you're a die-hard IF fan who is ready for the next step or a relative newcomer to the genre who would nonetheless like to try creating an IF game, this page can help you get started.
An obligatory plug: I maintain a set of interactive fiction pages on Brass Lantern. At Brass Lantern I have collected and annotated IF links, and have several years' worth of columns for your reading pleasure.
