There wasn’t an IF conference alongside PAX East this year, but people may be interested in the No Show Conference, an indie game conference running on the MIT campus July 14-15. It will have something of an IF community presence. (Not me. But other people. Note the talks by Clara Fernandez-Vara, Deirdra Kiai, and Jim Munroe.)
In particular, if you liked last year’s IF Demo Fair, you may be pleased to hear that there’s a demo hall as a significant part of the conference. Interactive fiction games and interface demos are welcome.
