Zack and Wiki Quest for Barbaros' Treasure.
agree! one of the best Wii motion programming, maybe the best non-motion plus controls, and it was released so early in Wii's lifetime
Silent Hill Shattered Memories was another good one rarely mentioned. (And also just a really good game that's rarely mentioned IMO)
Using motion and pointer controls to aim your torch, manipulate your environment to solve puzzles, and throw off attacking enemies felt great.
never tried it but sounds interesting, I'll add it on my Wii "to play" list :D
