""We consider Battlefield an online service...The single play experience is important. It's a great way to get fans into the experience, have them train up and get ready for multiplayer. And a lot of fans just enjoy having that single player experience. So I think you have to have both." "Clearly the multiplayer is the richer opportunity for us because of the services opportunity in keeping customers engaged 365 [days a year]. Fortunately, Battlefield, as a franchise, since the late '90s has been configured around multiplayer and I think that's why you're seeing such popularity around the design.""

Is their excuse for their generic campaign? I don't buy it. They have the Multiplayer as Disc 1 on the Xbox 360, obviously single player IS NOT training ground. 

This seems like a cheap responce to a mediocre campaine.

BF games always had better multiplayer than single player campaigns. COD's campaigns might be short, but at least they are a blast to play and (usually) have a very gripping story that moves the game along well.

Also, alot of reviews said that BF3's campaign doesn't really prepare you for multiplayer that much... the best way to do so is to play the co-op mode or jump right into the multiplayer.

so single playing campaing doen'ts matter anymore? they are just a way to prepare you to multiplayer...
