I would like to say, that enviroment and character moving and acting is perfect in FarCry 2 and I am SURE that if it will be possible change game engine on Ubisoft's Dunia engine (maybe its a expencive, but...) you will blow game world and will destroy all your competitor's. Because in Far Cry 2 you can fly, swim, crouch, fure and run very easy, as we breath, do not have to push many buttons to down or up on stairs, to jump etc. When you want run or sit, how many thing you do before? None, just sit, so let our virtual bodies do thing which easy in life, maybe little slower because of amunition, or wound, but easy. Also will be great to create possibilities to swim :). I love Far Cry 2 for freedom, for easyness, no time limits, you can walk and do your missions when YOU want, after campagn you can do many different thing, just play that game to understand what kind of ARMA 3 we want, easy fast, real. Just change your Engine, and we will make you rich
