World War II has been wrangled, exploited, used and reused over and over again in video games. True, there are sterling examples that continue to use the setting for more than just explosions and general bombastic chaos, like the Brothers in Arms series, but it is best that this sub-genre slowly ebb out into history if all we are going to get is Nazis, paratroopers and Russians with bad accents.
That is why Velvet Assassin looks so exciting. It is set in World War II, but it doesn't toss you into the frontlines of war. You are sabotaging the Nazi regime, behind enemy lines. You are the clandestine threat that will undermine their efforts.
