Yep, that's the one thing that still bugs me about even the latest games. To me it seems like their movements are too deliberate/precise, while not being random enough.

Like when humans are talking there are lots of tiny little movements all the time, even when we intend to stand mostly still. When a character in a game moves his arm it goes from point A to point B, stops immediately, and doesn't affect much of the rest of the body.
