Leonard Richardson talks about a number of free and open-source games he made, as well as his time running a goofy BBS as a kid. We discuss the experience of having dozens of strangers create their own riffs of a game he tossed together in a couple of days, writing interactive fiction as a stepping stone to writing non-interactive fiction, and Nethack code patches as a form of fanfiction.
