I like how this comes with a way to translate much of this to 6th and 7th Edition Call of Cthulhu. This game has great ideas you can use in other horror RPGs. YouTube's "Game Geeks RPG" Game Master Kurt Wiegel brought up in one of his review of "Pulp Cthulhu" that Actung! Cthulhu as already doing what "Pulp Cthulhu" tries to do for the Mythos.

Also you get to fight Nazis and isn't that always a good thing?
