If its a single player game, it's a single player game.
If its a multiplayer game, its a multiplayer game.
If you wanna play the game, you gotta play the game.
Really, I dont care about multiplayer support in a singple player game. I've really had about enough of multiplayer modes that are all rehashes of the SAME stuff.
Do something new.. and I'm all about it, and I could care less about the single player part. Hence 1942. Other than that its all been there and done that.
