Regardless of your stance on Nazis, one thing is pretty clear, occult Nazis are more fun than non-occult Nazis. For one thing their accents are more comical (see: overuse of 'ze' for 'the' and 'zis' for 'this'), and secondly they always tend to play (see: meddle) with forces they do not understand. Not in a "gee whiz, that science stuff sure is complicated" sense, more of a "holy crap, opening the gates to the Black Sun dimension could destroy the very fabric of our world" kind of thing.
But they mean well, actually they mean to use magic powers and forces to advance the cause of the Third Reich, but, they're definitely more fun. And just like the latter parts of Raiders of the Lost Ark, Nazi soldiers in search of mythical and fantastical devices and powers lend themselves better to the simple entertainment of watching them die in cool ways. A welcome diversion to the usual 'Nazis were actual human beings' approach of the more realistic World War II recreations.
Wolfenstein has a heritage that goes without saying, from essentially defining the first-person shooter genre to creating a great multiplayer flamethrower workout with Return to Castle Wolfenstein. Simply called Wolfenstein, this new title in the series sees id Software once again off-loading one of its most famous franchises to developer Raven Software, whose track record hasn't elevated above 'average' or 'good' since the PC classic Heretic.
