I’m left handed and never understood left handed mice at all. I write with my left and swing and kick left handed, but all gaming stuff has always been the same way anyone else does. I’m pretty sure up down left right switching to wasd is a function of that setup being more comfortable with the mouse to the right of the keyboard, correct?
correct, and I think games which needed action keys in addition to arrow keys (but no mouse) preferred arrow keys on the right so the left hand could handle the other moves and stuff.
I write with my left too but using right handed peripherals feels natural. I also use my phone right handed.
