The last couple of days have brought some interesting reads that weren’t announced on RAIF, so I’ll mention them here:
Trotting Krips’ review of Planetfall. I’ve never gotten around to playing this one myself.
Nick Montfort’s dissertation on nn, an IF development system he designed in the course of getting his doctorate at Penn. The dissertation runs to several hundred pages, so it’s not a light read, but I’d recommend a look to those interested in IF theory. Some of what he writes is fairly technical discussion of how his system works, and it’s difficult to judge its merits given that there aren’t any actual games written in it (as he admits himself); on the other hand, he also does a lot of theoretical definition of the different aspects of IF games.
