The best games I've found for the Wii are:

  1. Resident Evil 4 (but then, based on the games you listed, it does not sound as the kind of game you would enjoy)
  2. Mario Galaxy
  3. Metroid 3: Prime corruption

I can not offer advice on DS games, as I don't have one.
 
Here are some of the wacky, fun Wii games I have, and enjoy:

Raymans Raving Rabids I and II
Mario and Sonic at the Olympic Games
My Sims
Guitar Hero III
EA Playground
Cooking Mama: Cookoff
Warioware: Smooth Moves (wackiest of them all and a little 13-year-old boy humor)
 
Not a huge list....
