They're maybe slow, but not boring, because when you're into them (stealth games), your anticipate your enemy's move and wait to kill him when no one sees you. I've just finished Crysis, and most part of the game that plays in the jungle, you can finish with shooting with only pistols, if you played it stealthy.
It's a sad thing to see demos of the game and then to read couple months later, it's all been scraped.
I never really saw single comparison between XBOX360 and PS3 game that wasn't biased towards one or another console, and on top of that, they never were compared properly. If you want me to see differences, then at least show be the exact same things. Otherwise it's like showing the same thing with "xbox360" and "ps3" on sides of the video.
Well, I guess it's not a coincidence that MS/Epic decided to show this video right after we saw Killzone gameplay footage. Result is that when you go to N4G all you see is Gears of War 2 (insert 'comparison','world premiere','analysis' right after the title) plastered all over the main website. Quite bright move from MS side.
But I don't want to share my views here on PR moves, rather I'd like to try to explain how I personally feel about GoW2 and Killzone 2.
Killzon...
Yes, it will. Move on.
