Conclusion: If your a big fan of advanced wars or even Commanders: Attack of the Genos on XBLA and would enjoy playing in a more action oriented third person view you will enjoy Operation Darkness. Just be warned the action can slow down to a snails pace and playing missions over and over just to clear them can get tedious.
Excerpt: Operation Darkness has been marketed as the strategy RPG in which you're pitted against Hitler's supernatural forces of evil–including Vampires, werewolves, and even dragons–during the height of World War II. While the merger of fantasy and reality isn't an entirely new concept (think Vampire: the Masquerade), the premise is promising with the potential for great atmosphere and even whimsy.
Excerpt: The truth is that all reviews are subjective. Critics, reviewers, and gamers all bring the weight of their experiences and tastes with them to every game they play. I point this out because Operation Darkness nearly overwhelmed my critical reasoning skills. It's a game that hews so closely to my tastes that it might well have sprung wholly-formed from my own mind.
Summary: Operation Darkness starts like other any video game based on World War II: you play as part of a division of heroic Allies (British, in this case), and end up in a unit that specializes in behind-enemy-lines operations. You start taking the fight to Hitler, and get to hear lots of really old guns firing, bombs going off, and fighter planes flying overhead. Pretty basic stuff—you may as well be playing Super Call of Duty RPG .
