I love playing with others, that's why I play online games. I know DU will not run twice on the same PC, that's why I asked here if they have considered it, it will make it easier. SC and CS are two totally different games, one being FPS and the other an MMO, so I am unsure why your trying to say about CS.
As far as being effective, I totally disagree with your statement and its my own business on how I want to play . Each to their own I suppose.
