There is much to love about this RPG. First, it extends the already interesting Gumshoe game system used for such games as Ashen Stars, Trail of Cthulhu, Esoterrorists and Mutant City Blues. I've been itching to try out the investigation mechanics for Gumshoe, and this recent incarnation and extension of the ruleset affords me such additional rules the combat and cinematic chase rules to support the espionage/thriller genre.
Next, it also provides rule options to help emulate and support various subgenres of the spy thriller. There are rules for the interestingly-named subgenres: Burn ("psychological damage and the cost of heroism"), Dust ("gritty, lo-fi espionage"), Mirror ("hidden agendas and shifting alliances"), and Stakes ("higher purposes than mere survival or 'getting the job done'"). In addition to the Drives and Sources of Stability that we've seen in other flavors of Gumshoe, the Trust / Betrayal mechanics are particularly interesting and volatile in a espionage game (reminds me of Cold City / Hot War)!
Gunplay and cinematic chase rules look good from the emulation space, though I'd be remiss if I didn't say that proper playtesting should be done on my part before I can say if it's to my taste.
As for the vampire aspect -- great latitude is given to the GM and the players is choosing the type of vampires they're fighting (which is good to keep the surprises coming in a thriller), and the organization creation rules married with the classic genre pattern of starting at the bottom of the conspiracy pyramid and moving up through the ranks until dealing with the Big Bad (to borrow some Buffy terminology here) has really ratcheted up my desire to play this game as soon as possible! That's made easier by the sample vampires and their various minions also included in the book.
Well done, Pelgrane Press -- I look forward to future releases in this line!
