Not so much. A WWII combat first person shooter has an element of understanding the reality of what happened, historically, and appreciating the sacrifice and hardship. A near future apocalyptic destruction of the United States is a setting that nobody (at least nobody in the U.S.) should really want to see come to pass. While most (perhaps) don't let such fictional settings temper their mindset, regarding the future as they see it, I'm of the mind that more than a few do. There's a dark element of the entertainment industry (Movies, T.V., Games) that is bent on such a theme (and yes, it sells - but even that tends to be worrisome to a point).
Um, needless to say (I hope) - this is my take on such.
