hmm... all good games, though I'm going to tell you right not that Super Mario Galaxies is waaaay to short and waaaay to easy. It's not that great [unfirtunatly
]. They are making a second one, so if you want to get it I would suggest waiting 'till that one and hope that it's better.
As for the New Super Mario Bros: it's pretty fun. Though the multiplayer/co-op is crap, so be warned. Also, I would deffinatly suggest you get Metroid
As I said in the first post;
Super Mario Smash Bro's Brawl has to be one of the best games for the wii, especially for multiplayer, so that is a getter.
May I ask you a question? HOW IS MAD WORLD NOT YOU KINDA GAME?!
