One of my biggest gripes with Bethesda games is that they create these magnificent worlds that are alive but the animations for characters and creatures look like they are from the days of the Playstation 1. I know that Todd Howard has said that the animations were improved that there's some new engine (or at least elements) that drive these animations. When I'm playing Oblivion, I often walk from place to place, and I walk in the streets to make it more believable. However, the only walking animation in the Skyrim video has not sold me on the idea that animations are improved much. Maybe its just me but it still seems stiff and lifeless. I'm hoping to see the character's shoulders turn when you turn him, see his torso bend when walking up/down steps, etc. I don't want to see the "ice skating" animations when strafing from side to side. I'm hoping that these are vastly improved but I still don't know if they will be. Does anyone have any insight as to whether these things are actually improved in Skyrim or do you think we can expect the same old animations with just a bit more polish? If you think about it even Fallout: New Vegas had some improvements over Fallout 3. Specifically the "walking up steps" animation. The character actually took steps, it still didn't look quite right. Going back to Oblivion there was only one walking animation and it didn't matter where your character was walking or what he was doing, it was all the same.
Some may say that I'm being nit-picky, but this is one thing that I think can change the entire environment and is the #1 area that needs attention (at least cosmetically) in the Elder Scrolls series. Fixing these will make the world much, much more believable.
