CoD 2 has been averaging a 92 on gamerankings. Gamespot gave it an 8.8, same as the PC version with higher graphics score and lower value score.
Good:
Smooth (constant 60 fps), detailed graphics and great sound; aggressive enemy artificial intelligence; makes you really feel like a small part of a bigger war; varied campaign.
Bad:
Online multiplayer restricted to eight players (not totally true according to IW, that's just what's on the box but it can go higher) ; higher pricepoint than its pc counterpart
Kameo got a 8.7 from Gamespot, 9s across the board except for value. Apparently it's a little easy to burn right through the game.
Good:
Inventive, fun gameplay involves transforming into various cool, kooky creatures; plenty of variety will keep you guessing and entertained; drop-dead gorgeous visuals showcase the power of the xbox 360; beautifully composed orchestral score, as well as tons of amusing sound effects.
Bad:
Disjointed introduction may be frustrating; fairly short game at fewer than 10 hours in length (not everyone plays like you Greg...); two-player cooperative mode isn't very compelling.
GUN got a 6.4 on Gamespot, no surprise seeing as it really doesn't look any better than the current-gen versions, and the game was pretty bad to begin with.
Good:
Terrific voice acting; fun horseback riding; some intense, gory shooting action.
Bad:
Short storyline isn't made up for by shallow side missions; some noticeably undercooked elements of play; some of the violence and profanity feels too gratuitous; visuals don't take advantage of the xbox 360, looking bland and blurry; higher retail price than other versions for no good reason.
THAW got a 6.6, again it didn't get much of an upgrade at all, and the HD resolution only served to highlight all the flaws.
(is it just me, or is Neversoft turning into EA?)
NFS:MW got an 8.4 on all versions, not just the 360.
Good:
Compelling story mode; interesting bmx trick system; game contains a healthy dose of crunk juice; 360 controller's four shoulder buttons are perfect for playing this style of game.
Bad:
Character models and textures look pretty bad in HD resolutions; classic mode contains old levels that aren't exactly classic; graphical glitches further mar the game's visuals; story mode holds your hand every step of the way; costs $10 more than other versions for no good reason.
PGR3 hasn't got a review on Gamespot yet, but 1up gave it a perfect 10 while IGN gave it an 8.8... Interesting.
And there are a lot more to review, like PD0, King Kong (which looks fantastic for a port), and Condemned
