Zelda, Mario and Red Steel look like very good strong games.
I've played Red Steel and Carbon on the Wii they have setup in the staff room where my lass works.
Red Steel takes some getting used to, as you move your view with your motion, the analog stick is used for movement and the screen sensor is used for detecting where you're aiming. Fantastic when you get used to it.
Carbon on the other hand, was totally pick-up and play. Motion controls the car's steering. B is the accelerator and A is break, then you have Nitro and Handbrake attached to the D-Pad.
Easier using the Logitech steering wheel but still more than possible to use with the wiimote itself.
This said they've also added legacy controls, so you can just pop-in a GC Controller or Wiitroller and play like you did in the classic NFS Undergrounds.
Want to try out Mario Galaxy, and Zelda also looks quite fun.
