:I did not assume your nationality actually, more your continent.....  If you took offense to that I am sorry, that was not my intent.  That said, using two words seems better than one, to make it clearer to more readers.  A direct translation of the Japanese seems the best approach.  I have never called COD WAW COD 5, well I probably did when it came out, so never might be a tad strong.  The game is called Call of Duty, World at War.
