which one? and why?

I would say ryse.

They both look pretty damn good to me. Though which one ill like more is the better question for me :)

Killzone looks like ass in everything that isnt used as promotional video.

Ryse looks decent all around with nice character models.

Both look amazing graphically.

I'm surprised it took this long for someone to make this thread. It should get ugly in here rather quickly!

Both look stunning imo, but if I have to pick one I have to say Rise just for its character models and overall realism.

Single player - Ryse

Multiplayer - Killzone SF

In what way does this look ass? Honestly have you ever said ANYTHING positive about a Sony exclusie before? Cause there's no way in hell Shadowfall's graphics are ass, you're just being a bias hater by saying that. 

Anyways, will have to wait until I see more of the environments before I choose which one looks best. 

From what I have seen thus far, Ryse looks superior graphically. Killzone looks amazing and will probably end up being the better game IMO.

I really want this title with my day one X1. If amazon does the same (buy 2 get 1) they are doing for PS4, I will snag it, otherwise Forza and Dead Rising 3 are my priority come launch day.

Well I haven't seen either firsthand but from what I have, Ryse. The character models and facial animations are very impressive and the game overall is looking far better than I thought I'd ever give it credit for previously.

Killzone's cityscape graphics are amazing looking, but the visuals during the actual firefights really aren't overly impressive to me. Again, I need to see it right in front of me though.
