Prettiest game maybe. The AI is not good, about as good as Fallout which is pretty sad. They just take whatever path is available and come to you using whatever that enemy uses.
After having Stalker high level enemies come out after you in a classic box formation and hunt you down from cover this stuff is pitiful. The Stalker AI will try to box you in, create a crossfire situation and it never leaves cover unless forced. Very nasty. All there is here is some kind of power armor on a few baddies and they all try to fight you from the open. Easy meat for someone like me.
They say 15 hours gameplay. That is a pretty small game for a huge open area, which i doubt. I've walked all over Fallout 3 and NV and it's big, takes quite a while to get anywhere. The mod I'm playing now in Stalker is huge. You can walk for hours. Just exploring in these three games is fun.
