Do you know why people are still loving it? It never really changes. It's the same thing over and over. The only change was that it started becoming futuristic, now every cod game is becoming futuristic. People seem to dislike change in video games. It was the same thing in halo. Halo 4 changed a lot of halo multiplayer with the ordnance, load outs, etc. it still felt like halo, but a lot of it seemed different. If COD continues, It needs to change. They tried changing it with ghosts, but failed.
