I have had a live account for roughly two years now and I have played both Call of Duty and Halo. I enjoy both, but I put them in two COMPLETELY different categories. There are certain characterstics of COD that we all know and associate with the game and one of them is "killcams". Yes, its handy to know how and why you were killed in a match in COD because the game is so fast paced and its hard to keep up with things at times. On top of that, you tend to kill and die much more in COD than in most other shooters. In my opinion, Halo players have to play with a different strategy because the physics are different and the game is a bit more technical. For most "newbie" halo players, getting a kill is quite and accomplishment compared to getting a kill in COD.
I tend to be a traditionalist when it comes to video games and I'm having a rough time accepting the new improvements to Black Ops 2 and the killcams that are now being incorporated into Halo 4. Seriously.....killcams do not belong in Halo. It needs to stay in COD. I know that people talk about the whining and not knowing how or why you got killed, but thats how Halo has always been and the way it should stay. It's always taken a certain level of skill to play Halo and adding killcams will just make it more like a typical Call of Duty game.
