As a COD and Halo player (every one except Halo Wars), I see the differences in both. As a 15 presteige in COD, I end up running around with a SMG or Shotgun free aiming and early killing until I get the Chopper (which kills loads). Compare this to the more tactical HALO, where if you get caught in the open, you are toast. The more you work as a team, the easier the game is. In COD, if you have a good player, he/she will run around, get power ups (Bombers/Choppers), get 35 kills and the weaklings just sit in a corner camping. If you camp in HALO (Reach or 4), you are likely to get BACK STABBED ;-) Yes the BR (DMR) or whatever it is currently called is overpowered, but so is the Shotgun (at short range) and the Commando AR in COD Black OPS. I haven't bought black Ops 2, as I am bored of running around getting 20 kills per game in the same fashion. I liked what Reach brought. Where else can you shout 'EAT MY KNIFE' as you stab someone in the back or rugby tackle them to the ground before face stabbing them. All you get in COD is a 'target down' from a poorly paid actor ;-)
