I just don't think that just having that kind of camera control does any justice to a 3D battlefield. This type of camera control is what they use in Take Command Second Manassas.
They are unable to stay poinetd on any one bit action on the battlefield. If you want to look at the battle from a different direction, and rotate the camera, you loose the battle out of sight and have to move (pan) the camera.This is EXACTLY the issue I have with these kinds of 'rotate in place' cameras.
