Initially, I was very interested in this adventure path. Extreme settings (e.g., Chult, "The Unapproachable East") have long interested me. The Russian connection and the winter aspect spoke to me. I was even considering restarting my subscription, because of this AP.
However, in my mind, the Russian connection went too far with this adventure: http://paizo.com/products/btpy8wbv?Pathfinder-Adventure-Path-71-Rasputin-Mu st-Die. I would have found this kind of genre-bending cool when I was much younger. (Who DIDN'T was a raygun from "Expedition to the Barrier Peaks"?) But, this is too much for me today.
There's a chance I'll purchase some of the adventures in this path, but only individual ones that -- on their own -- interest me ... and definitely not "Rasputin Must Die".
