When I played JK back in the day I only used keyboard. Then when HL came out, the guns required the ability to aim well because they didnt have the insane amount of spread that the CRifle or RailDet had. So I went to the mouse, and played inverted to start.
Then a mod came out for HL, Rune-something, where you picked up all different suits with different powers like double armor, double firing rate, constant healing, all kinds of things. The problem with this mod was that there was a bug that wouldn't let you invert your mouse. So I had to learn how to play uninverted, and I did, and I havent gone back to inverted since. However, when I play Battlefield I use the joystick to fly planes, and joystick is always inverted for me.
