There will be 100 levels from Nintendo included. That is clearly as much of a "story mode" as any SMB game has ever contained.
Plus the capability to create your own levels spanning the entire legacy that is SMB (excluding the bastard that was US SMB2, though I actually really like that game).
There is no way you can really argue this game is not worth its stand-alone price.
