Most FPSs atleast have legs when you look down
Hmm. As far as I was aware, it wasn't all that common. I've certainly never played an FPS with legs. (Not that I'm a vast consumer of FPS, but still...
)
so my question is would you want to be able to look down and see a fully body you know torso, legs the whole nine yards?
Nope, not interested at all. The videos of the one Oblivion mod that did this.... looked pretty bad. And the Arma II video I saw that demonstrated this... really didn't do anything for me. Not sure what the point is. (Of course, I don't need legs & shoulders being thrown around to keep me from knowing my character isn't just "a camera and two forearms".) :shrug:
(edit: in a game where it has some actual in-game, gameplay reason to exist - like Mirror's Edge - having a full body is a good thing. But just for looks, in any random FPS? Meh.)
