MORPG?

MMO's on consoles have been wanted for a while but who says that you always have to be online? Why can't an RPG just have online elements and options. Fable 2 was possibly the first RPG to include online play but including online play hardly enhanced the experience. I say that an RPG doesn't have to be MMO or not, why not just include the option for online play? Instead of trying to do the whole game online just do a mission or objective with friends. Using a certain mission would rid the problem of making it an mmo but still include enough online play to make it possible to play with a friend.
