It's very close to being "burnt out" if not already turned into ash in terms of the flames of interest of WW2 as a gaming plot/theme.
Perhaps being a bit more original with the war idea would be a good bet, but looking at the options there isn't really anywhere one could have a look at: Humans vs. Aliens? Please, there is tonnes out there. Another war, perhaps? Well, perhaps but then some attempts to glorify war in a game may become "offensive" to some quarters of the world, certainly not from me.
