Today I learned about the Jogcon controller for PS1 & PS2:
This was a dualshock where the analog sticks are replaced by a dial with force feedback, so players could play Ridge Racer and really FEEL the road as if the dial was a steering wheel. I have no clue if it was good (probably not), but I do miss a good weird controller.
The steam controller was (and still is) fantastic. I once got a comfortable binding for the original System Shock, which already has a pretty untenable control scheme with a keyboard and mouse. Also its haptic feedback can play music.
