Its a great game with a great single player and an even better multi player, and should last for a good long time ......
the cover system may seem a little confusing at first, and is certainly not as simple as gears of war's "1 button everything" cover system. it is a little troubling at first because you go from 1st person to 3rd person, but after a while it is like second nature.
i would have gave the gameplay a 9 or a 10 but sometimes, especially in multi player, the guns will shoot like crap then good. you can aim and shoot at a guy with the same gun, in the same place, with him wearing the same armor, half the times you kill him, and half the time you etheir hit him and nothing happens or your gun completely misses. i realize it is trying to be realistic but a trained special ops solider should be able to hold a sub machine gun steady while he fires
other than the small problems it is a great game and should be givin a try, even if you never have played a tom clancy game or not
