Imma let you finish but I gotta say that COD World at War was the the best Treyarch COD game.
As far as Gears of War goes I have felt it broken since the first game. Gameplay was designed and intended to be a cover based third person shooter, it instead devolved into a shotgun spamming tumble around the ground mess. People complain about the addition of the sawed off shotgun to GOW3 but I felt it to be a much more balanced weapon than the Gnasher shotgun.
Lastly I hate, hate, hate, HATE threads about leaving Halo. Stop being a drama queen and just take your copy and trade it, break it or whatever you please to do with it and shut up. No one cares that you have been playing since Halo CE and were in a clan bought every legendary edition and made a Cortana body pillow.
If you are really going to stop playing then do it and move on.
