The main thing that stuck out was the going up hill with a normal walking animation.
When Geralt is going uphill his movement should reflect that, with his legs bending and things. It's not a major thing but it can stand out in this day and age.
Just like games that have stairs, some just re-use the same walk animation and have them "slide" up the stairs, and others actually have the character walk up the stairs how they should.
Hopefully that is something they will tweak before release and have the animation for walking up hill look more natural and not just be the same standard walk/run animation.
Apart from that I thought it was a great trailer, I loooooooved the environment, the world looked great and expansive and the way Geralt talked while hunting the Griffin and it leading into another side-quest on the way and actually have Geralt talk about hunting the Griffin.
I wonder if the hunts will all be scripted or is it random? Like if Geralt replays the same hunt will it play out the same? Can you take down the Griffin quicker then what the video showed? Will you always come across the same side-mission while doing it?
I hope that the hunting missions are random somewhat, and the monsters don't just stay in one specific area and follow a script/linear path, but can roam and things.
That was one of the things I hated about Dragon's Dogma, they had these EPIC beasts that were fun to fight but they didn't allow them to roam around and make the world feel dynamic, the cyclops was always here in this one area, the dragon was here in this area, the Griffin always attacked right here, it took away the sense of danger/suspense of finding them out in the wild.
