We didnt lose anything. I would rather play Halo4 than cod Halo4 is far more fun than cod I had the option: cod or Halo4. After overdosing on 'real world fps' for years, i went with Halo4 and dont regret it at all. After playing Halo4, i will be buying the next installment. I will not be buying 'black cod ops 6: zombie- nazi- afghan st733t l37hal pew pew part 2.11'.
Corndogburglar, I used to think like you, but cod does take skill, it's not as "campy" as you make it out to be. I recommend the championship series playlist, and I recommend giving it a good day or two, it's really actually challenging, requires teamwork to win etc. hard point and flag are amazing, and search can be a super exciting game mode if you or your friends make clutch intense plays
Anyways halo is my game of choice ive been playing since nov 2004 and the way to keep it going is to support it, and any tournaments run for it , such as agl, or any local events nearby. If you don't have any, then organize one, I've held a good 10 or so LANs in my garage when I was playing halo 3 and I drove cross states to play halo on LAN, not even for a tournament.
Everyone jut play the game they enjoy playing/like, support your game, no need to hate on other games success, your post makes it sound like you haven't even given the game a shot.
