There was a thread on women gamers and one of them said the last thing she wants to see looking down to kill a rat is her own cleavage.
She's not doing it right. She should keep her eyes focused on the monitor at all times.
Besides, if we get body adjustments during character generation, it should be easy to make whatever attributes you want if that was really an issue.
Seriously though, I hope she's joking. In Arma2 all that differs from 1st and 3rd person is the location of the camera. When using freelook, the head is actually moving, and the world changes since the eyepoint is where the eye should be rather than on a central pivot point. You see your hands, weapons, feel, shadow, your stance, blood textures on your uniform etc. Skyrim appears to have a lot of cliffs, right? Wouldn't it be awesome if we had to balance along a cliff edge, while looking down all you saw was an endless abyss?
