For starters, yes KZ 2 had some of the BEST AI, from the range of tactical movements they do to how they engage you. It had such a tactical feel to it and they did challenge you. Not once did I feel Halo 3 has "good ai" when I was playing it. It was just a lot of enemies being thrown at you. Probably the same people who think enemies flanking you in The last of us is "bad ai"
I would put 100$ in this being on easy difficulty too.
The game play in its self for me is exciting and something I am looking forward too.
They have shown that KZSF will have moments were you can play how you want, you can pace the game, your decision on how you tackle the objective, you can take your time in a sense.
The OWL in its self is incredible too, from the large amount of options it allows to how it will change how the game will be played. I don't think many people understand how much this will change and enhance the gameplay...
Yes graphically this part isn't all that good looking, but when you compare it to every other game we have seen... it is still one of the best looking, with only C3 beating it ( once you have a very high computer) but the art style of KZ:SF is more appealing to me either way.
KZ SF is breaking the typical linear balls to the wall non stop action to give us a new way of playing this game (this game as in KILLZONE) and if you look at current gen, hardly ANY FPS games offer this level of openness and freedom.
Obviously the game will have its fair share of non stop linear areas but to see there will be this more open areas is very good news, variety of how you play.
Also, the gameplay shown here always looks boring for any game shown, the REAL fun comes from you playing this part were YOU can decide how to tackle the mission, so really it's not the game or the mission you find boring, what you actually find boring is the decisions the guy playing made ( well not entirely, but more or less)
The OWL, so good.
