Lets start by saying I like both COD and Battlefield they are totally different in there own way, but I can't understand why most of the supposed reveiws are just the Battlefield Boys wanting to hate the game. Just because you don't like the game doesn't mean its a bad game. Lets put it another way, Adele is highly rated by many as being a brilliant singer. Personally I dont like her at all, but does that make her rubbish, no, its just not my type of thing but I wouldn't put on her reviews, buy something else.
People are saying how MW3 is so similiar to others in the series, well it is because it's a continuation of the the previous story. If they changed it about to much people would moan its not the same. If you were able to fly aircraft and drive tanks, the makers would get slaughtered by people saying there trying to make it like Battlefield.I buy COD's because I know what I will get, and it's what I like. You tell me a game which has a follow up to it that isn't the same. Battlefield BC's very similiar, then how about the Assasins Creeds, Mass Effects, Tiger Woods and of course all the FIFA's to name a few, how samey are they, yet do people moan like they do with COD.
With MW3 I loved the story. You play the roles of various characters in different countries, one minute in America another in Africa. They are short missions but all link togethor and the pace of the game leaves you feeling breathless at the end of them. The graphics look great ( I am using 1080p) the sound is wonderful through the surround sound (the Mrs would differ on that) and the game plays very smoothly at a frantic pace at times. I really enjoyed it and loving it again going through it on Veteran. Its another great chapter to the MW series.
The online is yes, very similiar to that of old but why change something people love. They have introduced some different modes, Kill confirmed for example is good fun and because of its type you don't get many campers.They have also brought back spec Ops and a mode similiar to horde (I cant remember exactly what its called) They have changed the kill streaks some what, and there are a few small changes, but in general its the sort of thing people expect and want when buying the COD's.
Alas the quick scopers are back, but at the moment there are few of them and hopefully it stays that way, you always get the campers but the fun of it for me is to find them and keep getting the easy kills as you know where they will be, and what shooting game doesn't have them.
So overall if you like the COD's storys and the online multiplayer then you will enjoy it. If you are tiring of it, then maybe its time to choose something else. Personally I love it.
One final thought, on the release date MW3 sold nearly 10 Million copies of the game, so you get a few people on here moaning, but with sales figure like that, it proves that COD is loved by so many and disliked by so few.
