The latest issue of The Escapist Magazine (which can be read in Second Life as well) has an article by Shannon Drake on the ARG Perplex City: Breaking the Fourth Wall. Ignore the first page with unhelpful comments such as ARGs “are growing up, moving away from experiments and marketing gimmicks” (referring to The Beast, Majestic and I Love Bees), and you’ll find some interesting chat about Perplex City from Andrea Philips.
