how about setting the game in the Israel / Arab conflict?
im of course talking about the 1948 war that started one of the conrevesial conflicts in history.
sure, the war lasted just one year and the estimated loss of human life is about 130 thousend. but it was still an intense war.
it fits RO2 because everyone still used WWII weapons, British and German. (ak47's were not exported then to anyone) so it's a good opportunity to add british weapons like the Sten, Enfield and Bren
they could also add a nice veriety of handmade weapons that were very commonly used in this war, like molotovs and even throwing stones.
think about it, no FPS ever touched this conflict ever. woudln't it be cool to actually play one of the most contevesial wars in history and experience how it was?
