Good thought there Infernal.
I wonder if anyone really invented anything controller-wise at all? Nintendo basically created everything we see today.
I hear people say that Nintendo didn't create the analog stick, cause it was on the Atari, and took a step back in technology with the d-pad. But think about it, you didn't need analog controls then.
Nintendo then brought back teh analog stick and used it in a game that needed it most, Super Mario 64, and it was an instant revolution. You could make Mario tip-toe, walk, then run without having to press any extra buttons. How cool was that!
To me, Nintendo is the king of controllers. No one knows jack without nintendo.
