It looks alright, but I am concerned with the lack of ambient sound design in this trailer.
All three of the original games had a very distinctive "sound" to the Zone -- a constant droning that really sucked you in and made you feel immersed, as if you were part of the place.

The breeze through grass, distant howls, thunder rolling in on the horizon...
all of it, was utterly perfect, and it held up for 3 full games with hundreds of hours put into each.

There's not even a hint of that with STALKER 2, even when they're sitting around a campfire.
I'll have to see/hear more before I get truly excited.

Without the ambient immersion, it might as well be another METRO.

The amount of special editions and what they offer extra worries me quite a bit. Other wise it looks great.
