I don't spend a lot of time looking at game controlers mainly because I'm either playing the game or off doing real world things, but I took a brief pause for a moment to consider something about the xbox controller: Why are there an A and B buttons? I understand why the buttons themselves must be there (obviously), but why call them A and B? I mean, X and Y make sense (X and Y being the axis in any two dimentional direction), as well as all the other buttons names, but why A and B? Am I the only person to consider this?
