Why dont games let you button map freely? (consoles)

Good question. Especially since some people have disabilities and may need certain configurations just to be able to play the games at all.

But as mentioned above, PS4 lets you remap the buttons universally.

~Edit~
Apparently on Xbox One as well.

I cannot believe I didn't know this, thank you for posting.
