Call of Duty Gamemodes.

I just want to ask a question to you people out there. Why do you script gamemodes and name them Call of Duty Modern Warfare 2, 4 etc.... when it's nothing like call of duty. It's more like battlefield. Call of Duty doesn't have capture zones. and it doesn't have ranks like Soldier, Assault, General... So please take some sense into your heads when scripting.
