You do understand that this is an open forum for open discussions...
The title of this forum was to attract people who hated Halo 3 so they can discuss their reasons why they prefer Call of Duty over it. They weren't asking for halo lovers like yourself to come onto this post trying to tell them that halo is a great game... because they obviously have a mixed opinion on it.
