Just watched it. Looking cool, but that's obvious.
Voice acting is mediocre. Subtitles don't match what characters say (eg old woman saying "brother has turned" and subtitles saying "brother's turned" etc) The quest and its conclusion is obvious from ten miles out. Don't mean to rail on the story department, but if it's going to portray moral ambiguity, it should be subtle about it (and the VA work did not help.) Unconvincingly trying to sell "ancient evil awakens", Johnny not pacing himself, and the old woman looks like she said something around the lines of "I will not grant you audience, but if you help this kid on a random fetch quest who will then convince me, I will be persuaded" when you first meet her in the video.
Also, to CDP, take note - Stop using that goddamn shaky cam that Game of Thrones is so fond of. It sucks ass. Static camera angles work much better.
Noted texture pop-in everywhere, from Novigrad where it played havoc with distant LOD, to Velen where trees and shadows kept popping in ten metres from Geralt, and low-res textures everywhere. Especially apparent in conversations eg - Geralt pacing about that pustule in the dungeon, and it's limbs come into view, and the textures look like something out of 1999, and you can see blocky meshes - not enough polygons?
Water physics still is very unrealistic - liked the blood diffusing into water, but the stock effects really hurt it eg. Aard does not create a wave, but multiple ripples like I was angling stones across a lake. Also, physics is not in sync with Geralt - I sometimes noticed ripples appearing in places he was about to set foot in before it happened. Grass physics need to be worked on - as of now, it looks like Geralt has an invisible force field around him that push roots away, but allows him to clip through longer grass. It is jarring. On that note, Geralt's hair, sword is clipping through everything.
Also, descriptions of random NPCs on their heads is disingenuous. Show, not tell - a poor man's attire should tell his financial straits, but there is a redundant speech bubble saying "Poor Man" above his head anyway. The names are cool for named characters, interactive people and objects, but being everywhere is not a good thing. Note that this is not inclusive of speech bubbles for dialog,which I think is fine just as it is (could use some text wrapping, but that's about it.)
Horse riding animations look bad. I expected better than RDR, but it looks like a modder's effort on Skyrim. Effort here would pay off big time, since players will be staring at a horse's ass for quite a bit of the game. Also, horse ass too shiny. Same goes for OTS camera angle - Geralt needs to be more in the centre of that camera, because as of right now it looks like it crawled out of a TPS.
On the upside, Novigrad looks good. Especially like the shadowing on NPCs and their routines - lot of effort went into those. No Man's Land looks appropriately bleak, though a little bare of clutter. Areas look organic, map looks good, and so does the draw distance. Will await more.
