First weeks, total fun, after that...look for another game
Then we move on to the multiplayer, where you'll spend hours and hours if you like FPS. First off I thought it was really good, had fun for maybe the first 10 hours, thought it was spectacular, then I started noting the many glitches this game had, and although they are patched, when they were on, they sucked a lot of fun out of the game, next, a lot of weapons are waaay overpowered, if you thought the M16 for Cod4 was overpowered, wait till you get shot with a FAMAS, no recoil super fast 3 round burst, or the UMP45, low recoil completely automatic and very high stopping power, or getting knifed 10 feet away because of all the perks, which by the way are also overpowered, and the killstreaks although a good idea on first notice the hundreth time you get blown up spawning by an AC 130 will get you wondering if it's really that fun. And lastly I think level design was very subpar in this installment, given the fact that there are lots of camping spots and personally I don't like them much, I miss the good old COD 4 maps. So sadly this game broke my COD fandom, which was alive sin COD 2, and now I move on to Bad company 2.
