I'm glad they did. some games don't need online play and this is one of them.
Hell the only ones i have heard complaining about the lack of online is just on the internet, none and I mean none of my friends want online play with NSMBW.
If it isn't turnbased it isn't worth playing (mostly)
And shepherds we shall be,
For Thee, my Lord, for Thee. Power hath descended forth from Thy hand, That our feet may swiftly carry out Thy command. So we shall flow a river forth to Thee And teeming with souls shall it ever be. In Nomine Patris, et Filii, et Spiritūs Sancti. -----The Boondock Saints
