Metroid Prime Trilogy. Possibly pointless if you have the first two for GameCube, though they add new features such as a Wiimote-based control scheme and an achievement system, but 3 is also available separately for the Wii. Unfortunately it's out of print in the U.S. and Australia, and the prices it goes for are often extortionate. And, of course, the Wii is region locked. I have yet to find it for a reasonable price and thus don't own it yet. However, this doesn't affect you since you, if memory serves, live in Germany.

What little I've played of Skyward Sword is also enjoyable, but you've said you hate Zelda so whatever. If you enjoy old-school platformers you can't go wrong with New Super Mario Bros. Wii. Though it's one of the hardest games in the series, so you've been warned.
