Wow, that's a ton of options you got there. So I'm just going to give you some opinions on each game you've mentioned.

Console Must Haves:

Uncharted 2
Batman: Arkham Asylum
Dead Space
Bayonetta

DLC Must Haves:

Braid
Scott Pilgrim
Castle Crashers

Good to very good games that are not must owns:

Infamous
ModNation Racers

Games you could live without:

Final Fantasy XIII
Ninja Gaiden Sigma 2 (it doesn't compare to the original Ninja Gaiden in any way, shape, or form)
God of War Collection (there's no reason to own it if you have the first two)
Modern Warfare 2 (COD4 is much cheaper and MUCH better)
Killzone 2

As for a Wii game, wait for Epic Mickey, Donkey Kong Country, or Kirby. Unless you don't own either of the Mario Galaxy's or New Super Mario Bros. yet.
