To be perfectly honest, I don't see why people care so much about the scores that games get in reviews. All that I care about is that it's a decent enough game that I can enjoy playing it and not finish it in some crazy time. I can't wait to be able to play it, unlikely as nobody I know actually has a PS3 afaik, most are 360 fanbois which is why I bought one. Want a blueray player so may actually buy one but who knows.
It also recieved a 5/5 in the official playstaion magazine review. Imo, official reviews never count for me, they all seem to give very biased reviews, ignoring flaws and longetivity. Happens on all consoles though.
It looks great, graphics look most likely best i've seen seen on a console etc. I just hope gameplay issues weren't forsaken for graphics/atmosphere. I still can't take any FPS on consoles seriously, I despise playing them with an analog stick, I don't mind third person shooters or action games but FPS make me want to drill my own head in with a tooth which I have plucked from a squirrel. Too used to using a mouse I guess. But then again i couldn't play the game on my PC.
PS Comparing Halo 3 to Killzone 2 graphics wise. Really, how low can you go.
