My Wii broke a year and a half ago. Now I have a working one.

The last 18 months have pretty much been dead in terms of Wii releases, so I wouldn't really bother if I were you  - you didn't miss anything special

Seriously though, to add to Rols list: GoldenEye 007 (it's a new game, not the N64 one), Silent Hill Shattered Memories (came out just around the time NSMBWii did, you may have missed it), De Blob 2 (3D platformer based on coloring a black and white world), NBA JAM (fun game if you can get it on the cheap), Endless Ocean 2 (don't underestimate this one, it's VERY good), Tatsunoko vs. Capcom, No More Heroes 2, Red Steel 2 (a MUST if you own a motion-plus), Metroid: Other M (don't believe all the hate, especially since it's going for cheap nowadays), Trauma Team (also very good game going for cheap), Epic Mickey (Warren Spector's dark Mickey Mouse game), CoD: Black Ops, MDK2 (they fit the entire Dreamcast game on WiiWare with excellent controls).

Also make sure to check out VC as some classics have finally made it like Chrono Trigger, Final Fantasy 3 (6), Mega Man X and more.

edit: also, Prince of Persia the Forgotten Sands (different game than the HD version)
