Very good trailer, but tech-wise overall it falls in line with the best games already out so i'm not sure what people are seeing. Art is pretty good too, and better tech compared to what was possible on PS3 helps for sure in achieving what looks like the best art direction and overall look in the series so far. Acting was believable thanks to good voices that match the characters and great character models/animations. That nate theme 4.0 tease at the end was very good, can't wait to hear the whole thing.
If i have to say something negative about it, is about ND's ability in making stupid, unappealing and generic human villains. Nadine looks just as terrible as the ones in the previous games (and TLOU).
