I think everyone's forgetting one thing about NSMBWii

[The Ghost of RubangB]

The game doesn't need nunchucks or Motion+.

Somebody could easily buy this game with 1 or 2 or 3 more remotes for a big Christmas party, or maybe pick up this game and Wii Play.

I bought 3 remotes and 3 nunchucks at Wii launch.
