I'll start by detailing points over the 3 parts giving you the timings so you can watch.
Part 1:
http://youtu.be/I2_msV2gGJQ?t=3m6s : This is a complicated issue... some people like it, some people don't... ultimately i hope we can disable 3rd person finishers and note that the game even goes into a slow motion. Also.. is it possible to kick or is it just part of the animation?
http://youtu.be/I2_msV2gGJQ?t=3m17s : Ok.. this fight had all sorts of weird things about it. Notice how the 1st arrow that hits the shield produces no effect and almost no sound as if there was no power in it? I'm not referring by the way to the sound produced by the string or projectile, i'm referring to the impact sound. After the second arrow that he misses he hits our character and its as if he didn't even felt it, no encumbering effects? The same goes to for target after he gets slashed he doesn't react to the hits. We did see though that there are indeed 1st person finishers which is nice although i can see some *teleport* happening in order to get the proper position for the animation which might turn out weird.
http://youtu.be/I2_msV2gGJQ?t=6m28s : I'm no expert in horse anatomy but i can tell there's something weird about that horse, i think its the back legs just don't have the right shape or something.. can't really complain about this though, maybe its some Skyrim specific breed. Its a fantasy game after all.
Part 2:
http://youtu.be/-7PMYnjGD6g?t=27s : I know this has been discussed to death, but i think we can all clearly see a huge delay here on the AI perception and reaction time after his m8 gets killed. I know time slows with aiming but you can see when that happens if you examine the fire, for the most part it wasn't in slow motion.
http://youtu.be/-7PMYnjGD6g?t=1m35s : Interestingly this is probably the best fight scene in the demo, the spider reactions are pretty good for each blow, although they were more blunt weapon effect reactions it was still a pretty awesome fight. hum...
http://youtu.be/-7PMYnjGD6g?t=5m6s : YES! MORE OF THIS PLZ
http://youtu.be/-7PMYnjGD6g?t=7m44s : Here is a big disappointment.. i though the spell would reveal ways out of the cavern and not objective direction... :\
Part 3:
http://youtu.be/FJAB2QGna_g?t=50s : Its kind weird that he manages to hit the mammoth from that distance with the shield.
http://youtu.be/FJAB2QGna_g?t=2m8s : I assume his the same guy who was thrown around and bitten by the dragon. How is he still alive? :S
http://youtu.be/FJAB2QGna_g?t=3m37s : Ok, for starters, that's a pretty big jump but whatever... the point here is.. he reaches the ground and... again no encumbering effect? No weight? His wielding a bloody huge axe and armor!!! I mean.. even without any armor it would be weird.
http://youtu.be/FJAB2QGna_g?t=3m53s : I'm pretty sure Pete said something about no terrain deformation... so what is that?
http://youtu.be/FJAB2QGna_g?t=4m8s : No.... Just No.. Noooooooooooooooo... *sigh*
So does are some points i wanted to make notion about... overall some of them were pretty expected.. specially regarding AI intelligence and the combat gameplay (looks a lot like Oblivion..). Don't take me wrong though, this game is gonna be amazing!
PS: before anyone tells it.. I know its a demo, and as the name says it, its a demonstration of the game, if you believe a lot of these issues are gonna disappear then i'm afraid your putting yourself on the road to disappointment. Please try to remain on topic.
