Both games are popular with military enthusiasts, and offer a more complete miliary style FPS experience. Arma 2 is very similiar in style and feel of OFP2DR, however the game arma 2 has a more simulated look to it and seems to be less "arcady". Operation flashpoint 2 is in competition with ARMA 2 from bohemia.

I just noticed that the etymology section of the article probably outweighs many entries in the Oxford etymology dictionary.
