That would be insanely cool.
I am always interested in more unique themes of historic FPS games. Games that are constantly about famous wars and battles such as those of WWII and modern wars get boring after a while. (though WWII has many less recognized battles and fronts that could make great games, like the Winter War, Second Sino-Japanese war, Anglo/Austro/Indo-Japanese war, Anglo-Italian War, and much more)
A new theme is always welcome, unless something entirely fresh comes on line for the Normandy theme (which would be very difficult, considering how overdone Normandy is in video games).
