Well I agree with Galaxy 1 and 2; both are exquisite platformers, and will probably never be matched. And I say that, because I SMG is the first 3D platformer that I've loved since Donkey Kong 64 (Yes Sunshine is a great game, but it lacks that thing). It has had the biggest impact on platform gaming since Mario 64, and just set a standard so high that nothing has matched even the first SMG game, except for SMG 2 which did the impossible and surpassed it.
Of course a lot are gonna say SMG is the better game (and I love it more), but it's more due to the fact that there was more awe and a surprise factor, and it set a high standard for SMG 2. But technically SMG 2 is the better game, and I've even grown to love it more.
The other games I believe deserve to be in that list are The Orange Box, Bioshock, UC2 and Batman. Still believe UC2 is a bit overrated, but it's an amazing game nonetheless. Assassins Creed 2 should definitely be there in my opinion, but can't really talk about the others.
And btw why no CoD? (note this is sarcastic, please don't start a war :P)
PS: Oh yeah, GTA 4 was the most disappointing game this gen along with GT5 (Sony killed the hype for me)
