Since the poll limits me to 7, I went only with ones from MW and onward, and also cut out Ghosts and AW due to them being very unpopular among the CoD community. If you do like one of those two, you can still list them in the comments. Same if you like any from before MW. I personally enjoy Black Ops the most. I do enjoy WaW, but I personally never found it to be as amazing as many say it is. Meanwhile, for me, Black Ops just feels right. I found the story to be very well done and the multiplayer to be very smooth and consistent. Also, it introduced Nuketown, arguably the best map in Call of Duty history. And you can shoot zombies as President Kennedy.
