Kingdom Hearts Re:Coded for DS, the story is the poorest in that series but the gameplay is actually good.
There is also Kirby Super Star Ultra, Dragon ball Origins 2, and if you're a DBZ fan and a RPG lover there is a DBZ RPG for DS called "Attack of the Saiyans". Megaman Star Force, and Final Fantasy 4 for DS, there are a few other games that escapes my mind at the moment.
For wii there is No More Heroes, New Super Mario Bros, Resident Evil 4, and uh,,,some other ones though I'm practically killing my brain trying to think what the others are as the Wii has some pretty bad games.(curiously enough I got more for the crap games then I did the good ones when I traded to Gamestop)
Look up on Goolge, best games for Wii.
