I thought Metroid Prime Corruption did a good job. Yes, it is a FPS that you point at the screen to aim and move with the joy stick (which makes whupping the bad guys MUCH easier IMO). You also get to use the remote to move Samus when she is in morph ball mode.

Super Mario Galaxy also takes advantage of the motion sensors. Several levels feature customized control routines for specific tasks (like tilting to control a manta-ray or a giant pinball).
