That's right Kirby, another reason is that Call of Duty games have ruined other games, everyone goes for the Call of Duty games over any other. Other game companies avoid making games during November because Call of Duty is coming out, and they know because of that, they won't sell many games. I was a big Call of Duty 4 fan, and then when Call of Duty 5 released the 'noob tube' ruined that for me, then even more so when Call of Duty 6 released. The 'One Man Army' perk is really stupid too, as you can bacically keep reloading your 'noob tube' over and over again. I respect all the game has achieved and done, but I choose not to play it myself. I would reccomend you don't get Call of Duty for the PC as the controls are horrible, and it's easy to hack.
1. Commando 2. OMA Danger Close Noob Tubes (as said earlier) 3. Awful spawns (I played today and kept getting spawn trapped on Rundown) 4. Inconsistent weapons 5. Spas-12 (it's a shotgun, but it has incredible range)
As for campers, you can complain, but there really is no way to fix them. There will always be campers in games like CoD, sitting in a corner with the cheapest weapon (in this case it's the FAMAS imo) and shooting anything that moves.
