Alot of people are saying CoD4 before KZ2. I'm saying the opposite.
Firstly, you'll get addicted with CoD4 multiplayer and I guarantee that you won't want to jump ship to KZ2 if you start off with CoD4 multiplayer.
Secondly, control wise, CoD4 is superior. If you loved Halo series, CoD series, Orange Box, Bioshock and all those other shooters, you will HATE KZ2's control scheme. I can understand that from a non-shooter lovers standpoint its okay, but it's completely unintuitive if you're familiar with FPS controls. There's definitely a difference between Halo and CoD4, they are both different BUT they share the same fundamentals, KZ2 is almost entirely different.
There's differentiating yourself from convention and competition, but it just felt like Guerilla were just trying to be different for the sake of being different.
Also, One thing I've loved about other shooters is that you'll find some parts will actually move your emotions (even slightly). You'll care if something happens to someone. Not in Killzone 2. The ISA is as heartless as the Helghast and your comrades are jerks. I really couldn't care less who won the war, it didn't stir any emotions.
One thing KZ2 definitely one ups most FPS is atmosphere. It's not just the graphics, it's the intensity that KZ2 creates. You literally feel like you're struggling to survive (especially on the tougher difficulties), it might not be because of you're actually struggling, it might just be your surroundings that create that feeling.
The only negative thing about the jump from KZ2 to CoD4 is graphics/atmosphere (Though CoD4 stirs the same feelings in multiplayer sometimes), The negative things you'll experience with the opposite is you'll hate KZ2's controls, Characters, Multiplayer and the fact that you know mostly where they got their ideas from and how few of their original ideas actually translated well into the game.
Don't get me wrong KZ2 is a great game, just don't play it after CoD4, because as a complete game it's inferior (not by much though). Also, Playing Cod4 second has the added benefit of you being closer to the launch date of MW2 once you are sick of CoD4, and trust me at that point none of these PS3 fans will be turning back to KZ2 once that drops (unless they like to look at the same pretty graphics over and over and over again, which alot will be mentioning to detract from the awesomeness that will be MW2).
