Shiggy gives a different reason for no online in NSMBWii

[gamelover2000]

I think games with local multiplayer that dont devide the screen in 2 (LBP, NSMB) dont need online.. if you have mates who wish to play with you... the game will be a laugh

I found NSMB and LBP VERY much alike, LBP superior due to level building and online sharing but both so immensly fun that I just wish both will sell a buttload (NSMB Obviously will but Sadly LBP is not even near it)
