Today , after some careful evaluation of Doom III at work , i was stunned that some people only would play the game if the mouse movement was inverted (when you move the mouse forward , the viewpoint in the game goes down).
I hate it , personally i think only flight simulators should have inverted mouse.
Just gimme normal mouse (when you move the mouse forward , the viewpoint goes up).
What do you use ? And WHY ?
Score @ work is at the moment 3 Normal - 3 Inverted SO i added them in this poll status (6 votes including my own).
