I know lag can be a factor here, but what if we can play in such a network in which all players are from the Xbox 360, Playstation 3, and the PC? Some of my friends have Call of Duty 4: Modern Warfare, Call of Duty: World at War, and Call of Duty: Modern Warfare 2 on the Playstation 3 and I want to play with some of them but at the same time, I also want to meet new people. I've checked the site. I have no idea how the networking works with the game, more rather less Live/Playstation Network/Steam. I know there's some protocol or something that's preventing such unification.
I don't care how much advantageous it is on playing on mouse or how advantageous it is on playing on a gamepad. I personally don't care what's the difference.
Anyways, think about it. Wouldn't it be revolutionary? A universal console/PC network for multiplayer?
Then again, of couse, lag is a factor... x_x
