Tomorrow, May 10, there’s a #theoryclub meetup about CYOA structures on ifMUD. Details and some reading suggestions here. I am not going to be able to be there myself this time, but there’s an appointed deputy MC/transcript-taker, and I’ll post the results when I get them back.
May 17th in London, GameCamp is a one-day game jam and unconference. Again, I am not going to be able to be there myself, but I know several interactive narrative-interested folks are planning to attend, and it has the reputation of being a cool thing. Some tickets are still available.
May 25th is the next meetup of the Oxford/London meetup group, in Oxford this month.
