I guess it is never too late ;-), this game is almost 1 year old and I started to play it today, I have to say that is one of the best (graphically talking) games I've played for the PS3, of course, KillZone 3 is one of my favorites too. And if I'm saying that in the Play 3 looks damn good I don't want to know (well, I do) want to see it in a well powered computer.
I've just played it for about 3 hours, the story is going good and the missions are pretty straightforward so far maybe not that easy like in Call of Duty where everything is pre-stablished and just have to follow the path.
On the things that I don't like... the enemies disappear once you have killed them, and I don't mean when you kill them, get away and then get back.. they disappear just seconds after you killed them, and that's not good, please don't tell me it is because they want to save resources because they were there before you killed them so, there is no need to save nothing (unless a wave of enemies came to you).
Back to the graphics, they look amazing. I'll be playing this thing for a couple of weeks, maybe more if the multiplayer is still entertaining, Batman Arkham City will have to wait.
