Frankly I was a little disappointed. I was hoping for some clever new locales that would inspire me to greater heights in my Call of Cthulhu campaign, and instead what I got was a pastiche of old Lovecraftian locales clearly discernible under a thin coating of revised description. Heck, one, "Dark Carnival" even used the name of a Chaosium Adventure for Call of Cthulhu likewise set in an evil carnival.
There were several useful ideas in the book, but all in all, I'm not sure it was worth the price. Had it had even a few line drawings of the locales, the worth of the book would have been beyond dispute. Alas, there were none. Even more annoying than the usual horrific grammar, punctuation and spelling errors I've come to expect from Postmortem Studios, was the total cop-out of some of the locales. Really? You're presenting DARFUR as a location for a modern horror campaign, and "the horror here is man's inhumanity to man?" I think we all get that Darfur is one screwed up place where a lot of people are suffering because of human greed and evil, but it's not the sort of thing that is implied by the subtitle "A Modern Horror Roleplaying Sourcebook." In fact there are several locations here where the deadly phrase beginning with "the horror here..." is employed to serve notice to the reader that the "horror" will be something like "being isolated," or "being faced with starvation." Come on, Postmortem, I can get that from the local newspaper; what I wanted from you was, you know, HORROR stuff....
As I said, I was a tad disappointed by these issues. However, having said that, there are several locations which are not previously done much better by other companies (Chaosium's "The Mountains of Madness" for example in preference to the author's pastiche of Lovecraft's theme) or are not cop-outs in terms of actual horrors that might be very interesting to work with. One, "Sideways Street," in fact, provides an excellent germ for some very interesting role-playing, though again it lacks somewhat in originality since it seems to be reflective of "Diagonally" in the Harry Potter series, with a bit of the shops from "A Mysterious Pentad" and some of Clive Barker's work thrown in.
If you have a spare $7.50 floating around that you simply can't find any use for, then use it to buy this book. Otherwise, pass on to something more fleshed out and complete to work with.
