Because they have to put effort to implement it haha. With PS3 and 360 they are simply adding online to a centralized system where all they have to do is follow guidelines. With Wii, it's an open network where it's the dev choice to use any system they want. In words sounds pretty good, but in actuality it just means more time and effort to make it work and implement it, which 3rd party devs on Wii don't like to do anyways haha. So that's probably why. Although companies like EA seem to be using their central system EA Nation such that they can put it in more titles which is good but still NFS series doesn't have it.
