The amount of bias in this thread is just staggering. Can't we all just enjoy our exclusives without bashing the others? I mean I understand comparisons or giving reasons why you like x game over y game, but to actually say y game sucks is just ridiculous.
Reach looks pretty darn good from those screenshots, to actually say they suck is just blatantly bias. And as others have said, a comparison can't really be done until the game has released. However, when it comes out it can go either for or against it. It could have even better visuals as seen in the pics, or they may find they were too ambitious and have to scale it back a little. Which is a reason I think people on the 360 side are at fault as well when they say Reach will have this and that, or be better in certain ways, when no one has played it nor do they know what the final product will be like. Either way, I'm sure it will be fun and above Halo 3 in visuals.
It's also pretty dumb for someone to say one is better as a fact, when it's truly just an opinion. Just because Killzone doesn't have something that Halo has/will have doesn't make Halo BETTER (or vice versa), it makes it DIFFERENT. Not every FPS is going to be the same, nor should it. Otherwise these games would begin to be very boring.
One last thing, I don't understand when people say that FPS controls on the PS3 suck. I've played Halo on 360 and various FPS on PS3, and for me it's pretty much the same. The only difference, besides slight variations in sensitivity of the axes, is the positioning of the your hands on the controller. Even my buddy, a Halo fan, doesn't get all the fuss about controls. I personally prefer the alligned analog sticks of the DS3, but have never found the 360's controller unusable. Now I know Killzone's default settings have a lower sensitivity for the axes, from what I have heard it is to create a more weighted/realistic feel, which I actually like. But for those who don't, it just takes a quick trip to the axes sensitivity option to fix it.
