This is a weird one, but I’d love to see a reimplementation of the sensor bar. The gyro controls haven’t cut it for me. I like how the Wii U game pad had the sensor bar built in to the bezel. The real engineering nightmare would be squeezing IR cameras into the top of the Joycon
I’d like the sensor bar too. Rail shooters just do not feel the same trying it with gyro, since the positioning is off relative to the screen without a reference point. Sensor bar made it more like using those arcade light guns.
