Mw3 was too different from mw1 and mw2. mw1 and mw2s campaign was much better that mw3s campaign. mw1 and mw2= 9. mw3=7
The BAD:
To be honest MW3 felt like a step backwards compared to the MW1 & MW2.story sucked and was way to easy. The story was a complete and utter disappointment comparing MW1 & MW2 to MW3 story and was The story was to short .As for the Multi-player gameplay, the weapons do a little to much damage, recoil is worse than MW2, the maps are to wide open Not enough cover and the health decreased.
The GOOD :
The Multi-Player did have some improvements such as accuracy, ammo per clip, and scopes wobble less. The Maps are bigger.
