Tell me what quality games I've missed since NSMBW.

Roll pretty much nailed everything

but he didnt stress Sin and punishment 2 enough... get it, have it be your first pick up.

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)

I like many in rols list but I'd replace half of them with Metroid Other M easily.

I'm planning on passing up Metroid unless I find it cheap.

I've already been intending to get Tatsunoko vs Capcom, Goldeneye, and SMG2 (all three are the main reasons, along with the obvious Skyward Sword, why I got a new Wii).

The rest, I intend to look into.

RolStoppable gave you every game I was thinking of.

Like rol said, all great games.

But seriously, look at Tri, Galaxy 2 at least. Great games.

But yeah, you missed a fair bit from the year of the Wii ;)

JUST DANCE 2!!!!!!!!!!!!!!!!!!!!!!

Sin & Punishment 2, Silent Hill: Shattered Memories, Fragile Dreams, No More Heroes 2, Red Steel 2, Tatsunoko Vs Capcom, Super Mario Galaxy 2, Monster Hunter Tri, Donkey Kong Country Returns, Epic Mickey, 007 Goldeneye
