Quite a bit over the months it seems
lol, I rarely watch reviews/previews/video's of games as they have a habit of spoiling games badly. But I had a look at the video and my word it really does look impressive.
Some of the things that give it an almost real look being the animation, just a little movement of the shoulders back and forth walking or running, such a small increase in movement but add's massively, almost ridiculously to the realism. The movement really did feel brilliant, and the lighting, its amazing how lighting can make even a fairly plain texture look so much more realistic.
The engine looks incredibly impressive from that video, praying the final version isn't toned way down and it turns out the video was somehow faked, if its not, wow.
