Why is everyone bashing Call of Duty just for the sake of it being Call of Duty? Honestly, everyone who blindly hates it is worse than the games themselves. The singleplayer campaigns have been getting worse since Black Ops, but seeing a new developer with Advanced Warfare can give us hope for a game more like MW1&2.
Additional note: Yes, I know Sledgehammer developed part of MW3, but only part of it. I'd like to see what they do with all of it. I never play CoD's multiplayer anyway.
