This.

If they try and change it to COD, it'll be the end of Halo for me.

Fortunately I really don't think they will.

Well not necessarily. 

I personally feel that battles in Halo dont have a true war-like feel to them. To put it in a way we all can understand, the Halo ODST commercial. The part where the guy drops in and comes out of his pod to see a hellish battle raging.......we felt nothing remotely close to that in the actual game.

As a HUGE Halo fan, I want that ODST commercial feel in actual gameplay. Even the Halo Reach commercial where the Spartan delievers the bomb inside the covenant ship.....that too was a feel or true war and battle that the actual game didnt accomplish as well. 

But thats me. 

don't get your hopes up. No game period can come close to what was portrayed in those two trailers without being far too scripted. Gaming still has a long way to go. Maybe in 10 years you will be able to experience something like those trailers accidently in game.

Im not saying that Halo should copy COD gameplay but copy its atmosphere. Because its that that is closest thing to a real war atmosphere. 

Mix Halo universe and storytelling with COD war atmosphere is what I personally want.
