Yeah i agree but i think this ship has long sailed - over the shoulder cameras are pretty much everywhere these days. I avoided several 3rd person perspective games for this reason alone (some even had me feel nauseous) and eventually had to force myself to get used to it since i wanted to play some games that switched to it (e.g. Mass Effect 3). Nowadays i can play a game using it without feeling off but i still prefer it when games put the character at the center of the screen.

(also i yelled at more than one game that had an option to switch shoulder but not put the character at the center - if you are bothering to implement this why not also add the center option? :-P)
