And while I doubt it would be all too easy to impliment, I'd love to just see my body. I think this would do great in removing that feeling.
I want to look down and see my torso, my legs and feet, I want to see my arms swinging slightly when I look to the side, or heavily when I'm running.
This would do a whole lot when it comes down to immersion and would surely make the game a million times better.
