Mainly Because COD has pretty terrible controls. It's way to fast and is more or less of a twitch shooter with terrible design flaws. Killzone is slower yeah, but it is way more tactital and it takes more skill to play properly than COD. Though I do say, Killzone 2 multiplayer has gone to shit with spawn campers, rocket launchers noobs and loud obnoxious kids who teabag everything, you might as well be playing COD.
