I only remember playing Duck Hunt with Nintendo Zapper but I believe it had more games I just don't remember playing them. I remember the paddle controller for Atari but I was grown before I really appreciated them .
The Power Pad is my favorite from my childhood but I only remember the Track & Field game but as a kid that was enough & justified the giant pad .
I don't really like VR for some reason so I have missed out on the last few generations of secondary platforms so PlayStation Move is still my all time favorite secondary platform.
What are your favorites?
