So I bought the Call of Duty: War Collection (Xbox 360) which includes Call of Duty 2, Call of Duty 3, and Call of Duty World at War.  
I just finished Call of Duty 2 and started Call of Duty 3.  Wow, what a difference.  Call of Duty 3 seems like such crap after playing a very well polished game, for it's time of course.
Compared to Call of Duty 2, Call of Duty 3 has horrible controls, tons of bugs/glitches, and horrible AI.  I've seen enemies float off into the sky, teammates run right in front of enemies and neither of them shoot at each other, and I've shot enemies at point blank range and they don't go down, took 4 or 5 shots until they actually went down.  Also, what is with the shooting guys and the helmet pops into the air 4 feet??  And the cheesy dialog... well I guess that is fairy common in a lot of shooters now anyway.
I think I'm still less than a quarter threw the game, so I may for more comments later.

I didn't think 3 was all that bad, personally. 
 
I don't know, it's been a few years, but I didn't have a whole lot glitching problems, though I stayed mostly to campaign, considering I had a hard time finding a match with no internet at the time. Maybe it's just it's XBL connection?

i played it on the wii and liked it. i wish it had been on pc. it would have been a second uo
