The gamesradar guy concurs that the level designs and graphics are pretty tight. It's the controls that irked him, to the point that he would give it a 5. This is somewhat concerning, especially for a FPS's MP because I'm not sure the "feel" of a FPS is something that can be easily corrected. Most console FPS games don't completely click with me because I never feel at one with the controls. Halo is really the only console FPS that has ever felt comfortable for me because it has just the right amount of auto-aiming and analog stick sensitivity.
COD4 really clicked with me, for some reason. It just felt spot on, to a point where I honestly preferred gamepad controls to kb+m. Halo 3 is a recent one that you can tell was designed from the ground up for a controller and just
works, but it still doesn't feel as good as COD4. Although, that may just be because I'm a bit tired of the bulletsponge stuff, making combat less satisfying.
In regards to Killzone 2, I'm not taking previews seriously at this point; post funny tinfoil hat images if you want, but there is no way I'm going to be convinced that media in general isn't extra critical of Killzone 2. There have just been too many odd complaints that were nowhere to be seen when the same dudes previewed other games. And hey, I can understand why, but at some point they need to let it go. And when they
aren't critical, I worry that they are doing the whole "sacred preview build" shit, which also sucks.
No, if I'm concerned about controls, it's because Guerrilla has made it that way. I remember playing Halo 2 right after playing Killzone, and at that point it dawned on me exactly how god awful the controls in Killzone were.
